DevCorner: Underapprechiated game engines

In my never ending search for a FOSS game engine that is usable for game modding with out having to reinvent the wheel (nor requiring to be a C++ code master) & having decent tools for content creation (because I am spoiled and think that is a minimum requirement for a game engine) I have become quite disillusioned lately. That is because *spoiler alert* sadly there is none so far... but a few are close luckily.

The usual contenders for 3D action games are your mixed assortment of idTech based engines, most notably ioQuake3. There are a few upcoming contenders like Unvanquished's Daemon engine (which is a mix of ET:Wolf, ioQuake3 and Xreal) and a yet to emerge idTech4 based champion (my uninformed guess is that it will be dhewm3). But all of them lack a decent game-play scripting function.
On the other side of the idTech spectrum, there is the idTech1 based granddaddy DarkPlaces, which while having advanced to an quite impressive feature set, suffers a quite a bit from its nut-bolted & mostly undocumented client side add-on on the already a bit arcane script language QuakeC.

Interestingly the idTech2 based engines get little attention though. I have highlighted a few nice game projects based in it in the past, but it is probably due to the fact that each project is hacking on their own engine fork, that none has gained prominence as a game engine on it's own. But feature wise the engines behind AlienArena, Overdose and Warsow are probably the most advanced.
The last one of these, has been probably the most overlooked, with the game itself not exactly open-source friendly and the engine being developed more or less behind closed doors. It seems however that this has changed now, although given recent project news it is unclear what made them change their approach. But an all new version of it is now on Github with the main developer mentioning a few really nice changes here. Let's hope it isn't just a "source-drop" of a dying project, as after digging into it a bit (the documentation is really fragmented and lacking) I have to say that it includes a few really awesome features not commonly seen in other FOSS engines:
Besides being really performant, it is fully scriptable and has some quite unique multiplayer features like awards, friendlists and persistent game statistics. It also seems to make good process in having easy to edit GLSL shaders, which I have realized is a much rarer feature than I originally thought. Last but not least it has a really modern looking and fully scriptable menu and HUD.

Ah and before I move on to non-idTech based engines I should mention Engoo for those looking for a modernized software rendering engine based on idTech1 (there was some controversy over it, so I am trying to show some support for its further development here).

Ok, that covered, what are some maybe under appreciated non-idTech 3D engines?
First of all I should probably mention the well known ones for the sake of completeness: Cube2, Ogre3D and the new big player Torque3D. All of which are IMHO still failing to provide a good platform for easy game creation (mainly due, following the same order: in-fexibility & lack of scripting; huge mess of independent parts & bad toolchain; lack of Linux port & buggy and overly complicated toolchain).

One of the shining but lesser known examples of trying to improve the status quo is the jMoneky3 engine. Even though it is still a bit bare-bone (e.g. lacking game frameworks) the nicely integrated SDK and the great new node based GLSL shader editor keeps on attracting my attention. Similary the BlenderGameEngine sure has a few great advantages due to its tight integration. Sadly it seems to be the unliked stepchild of the Blender3D project though, which some quite serious limitations and awesome additions like the candy branch never reaching the the main release.

Then there are the still very much alive big names of the past: Irrlicht and Crystal Space. I am not exactly sure why those never quite reached the required mass to become the engines of choice, but I guess the license mess around Irrklang (and other non free but more or less required addons) and the CS Yo Frankie disaster might have to do with it. But at least Crystal Space was accepted as a hosting organization for this year's GSoC again, so they must be doing something right.

Last but not least, I would like to give a mention to a relatively new contender: Octaforge, which has supplied a steady stream of updated betas lately. The interesting things about Octaforge is that it takes all the good things from Cube2 and combines it with a much updated renderer (Tesseract) and full lua script support. But sadly it isn't quite there yet, and the move to a scripting language required the removal of all the nice game-code that it inherited from Cube2.

As closing remarks I have to admit that this article was rather lopsided towards FPS game engines (and more general purpose ones). Of course there are many great other game engines in the FOSS sphere that focus on RTS or (MMO)RPG games etc. I do however feel that many of the grievances voiced here probably apply there too, but maybe it isn't quite as frustrating there as in the FPS genre.
But if you have some better insights into those type of engines feel free to comment below!

tl;dr: the author (as an old school modder) is frustrated that after all these years there still isn't an FOSS FPS engine that can be modded as comfortably as the Half-Life2 engine or UDK. Don't miss the new qfusion stuff though.

OverDose now officially... hmm?... open-source?

Somehow I was under the impression that the team behind Overdose had realized some time ago that by using the idTech2 base they would be bound to the GPL licensing requirements, and abandoned plans to buy a separate license just to keep the code closed... however that was never officially announced until now:

This now means that OverDose is totally open, totally moddable, and totally complete with its own mod tools, which include level compilers, map editors, font tools, custom HD .RoQ video compilers, texture compression tools, model format tools… Lets just say, a decent package of tools with a fully written SDK and developer wiki. So you don’t just get the game source code, you get the full shebang, everything. Of course media still belongs to OverDose, but the above should be great news to any mod people or budding game makers.
Whats more, the code is available… Right now! Get in touch at odium@team-blur-games.com for a link to the codebase which is constantly updated! Any budding coders out there who want to be part of the OverDose team be sure to get in touch, we always, ALWAYS need more coders ;)

In their recent news they also mention that they have realized that keeping the source closed doesn't help against hackers (a realization that comes better late then never :) ) and that their updated (GTK-Radiant based) level-editor is now available. That they add all their other (AFAIK Windows only) tools into the open-source mix too is an unexpected but very nice bonus!

Some recent automatic foliage tests

I assume by asking for code access they will point you to the "hidden" repository here, but giving them some positive feedback by asking for it, will probably be the "right thing"tm to do ;)

Oh and don't miss the long WIP thread with some nice (but over post-processed) screens here.

WIP weapon model

Last but not least: To avoid sounding too negative *again*, I think this is a great development and this could become a really nice open-source modding platform, specially if they make at least a base set of assets available under a more liberal license *hint* ;) So show them some support by helping out or maybe donating.

The Big corrections round-up post (and TA contest)

So... you might have followed the lengthy discussion in the comment section of this blog entry of mine from last week... if you didn't don't worry you didn't miss anything important :p

However I was corrected in quite a few things (besides all the disagreements), so I though it would be good to post a sort of "counter statement" to clear up some recent mess-ups by me:

First of all, the developers from Q2W informed us that in fact most (but not all) of their art assets are CC-by-SA or GPL, which is great. They have also released a Linux installer now, so feel free to check it out if you are gaming on this platform (like me). Oh and I have also updated the video to a newer one, in case you didn't notice yet.

Also, and I am to be honest quite surprised by this, OverDose does in fact have an open source-code repository since some time now, where you can download the source to the engine and some of the cool in-house tools they have developed. No clearly visible notice on the website about this however :-/ Even on the wiki they have no link to it I think.

Ah, and I was also informed that UFO:AI has now released an Linux version of the mentioned 2.4 RC.

Otherwise? Stunt-Rally does indeed have a player-collision option, which I somehow missed... but at least I am not the only one who feels that the physics are a bit off :p

Last but not least, and that is the only real news in this post:
The rather early in development steam-punk themed MMORPG Tempest in the Aether are hosting an art contest in collaboration with OGA too (to celebrate their first release). A bit of a pity that it will probably be somewhat overlooked due to the big OGA contest mentioned in Bart's previous post, but maybe you want to contribute to this game as well.

P.S.: Criticize me all you want, and I am open to corrections as you can see, but don't expect me become a "proper" journalist! After all this is the "splatter zone" :p

The Big idTech 2 round-up post

Hello fans ;) Today we get back to the main business of this blog: gaming news!

And of course my favorite genre: FPS (forevar!)... specifically everything related to the Quake2 engine (idTech2).

The reason is that we got a nice mail from the developers of Quake2World, which I had not really on my radar as still under development. But now they released a public beta, which I have not tried yet as there isn't a Linux download (yet).

Edit: Updated to newer video

But judging from the pictures and videos, I am was quite sure that DFSG standards are not fulfilled... and they know and don't care (very short sighted... but well).

So that is why I decided that they don't deserve a news post all by themselves :p

Low and behold... an update on all Q2 based games that *are* on my radar:

AlienArena is preparing for a new release with a reloaded trailer and some update one engine improvements:

What's new in AlienArena

Ya3dag, also released a new version recently and I still think its cool in-game editing features should be picked up by some other idTech2 engines. Can't be that hard to port...
Especially for UFO:AI it might be a nice way to modify missions. Speaking of which... they are also preparing a new version 2.4 and released an RC (changelog) recently. Again no Linux download, so I am skipping it for now. They have however almost reached full FOSS status of their sound-effects... at least that is what they say, the graphic they posted says CC-sampling plus though, which is AFAIK not FOSS compatible :(

Now to the games that don't show any real visible progress: War§ow is just posting stupid stuff interesting trivia on their blog. However I don't consider the long awaited 0.7 release vapourware yet.
Another matter in the vapourware category is OverDose though... in development since what feels like at least a decade, and still no release anywhere near (which is also their excuse why they don't share their nice engine improvements or for that matter any source-code all together >:( ). However they recently posted a lengthy news on Moddb in what seems to be an attempt to jump on the current "Kickstarter" bandwagon. Think what you want of that... but they are for sure not getting any of my cash before there isn't a engine-source release...

A bunch of updates

Very creative headline, I know... but news of various games were piling up in my "should post about it on FreeGamer" link-list... yet I never really felt like actually writing an article about. So some of it might be old news... but hey at least it hasn't been featured here AFAIK.

So, where to start?

Maybe with some nice puzzle games: Rezerwar is a pretty nice mixture of a pipes game and some sort of tetris, and it was even created using only open-source software. Another pipes game is Cooldown, which might be worth to check out, too. Graphically a bit more advanced is Octaspire: Crates, a block movement type game or something like that ;) But see for yourself:

Octaspire:Crates Tutorial

A non puzzle game worth checking out are Hero of Allacrost (a 2D RPG), which recently had it's DEMO 1.0 release. Another, albeit 3D RPG (engine) is DNT (DccNiTghtmare), which is set in a "satirical post-apocalyptical world".

If you are following the development of the promising turn based colony game Unknown Horizons (aka the artist formerly known as OpenAnno), their new development blog might be of interest. Oh and did I mention that FreeCol also got a bunch of updates lately?

Very neat is also the recent release of FreeOrion, a turn based space colonization game. It still lacks some important features to be really playable (combat and diplomacy), but otherwise it is already a pretty good looking game:

FreeOrion

Another game currently heavily updated game (engine) is OSARE, which aims to be a fully featured base to build Diablo like story lines/games with. An already slightly outdated (v0.08, newest v0.09) shows what can be done already:

OSARE loot drops

Another interesting project I came across lately is the Darkplaces based Blood Omicide, which is of course sadly based on copyrighted material. Overdose, a recently already mentioned open-source "in engine but not in media" (and even the engine code has yet to be released) game has recently shown some rather nice enemy model screen-shots. Furthermore their newest video is quite amazing in regards to the light rendering.

A game-engine and the games based on it that is probably vastly under-reported here on FreeGamer, is the Spring RTS engine. I guess it might be due to my dislike of Total Annihilation like RTS, but there is actually one (with public domain licensed media) that strays from that kind of RTS concept: Kernel Panic puts you right inside of a PC, and has quite a bit of nice uncommon game modi that break up the usual RTS grind.

Kernel Panic promo

I guess that's all for today... my link-list is not yet completely empty, but the rest will have to wait for another day ;)

Quake2 engine day ;)

Ok, today I have quite a lot of stuff, and its all Quake2 related :p Believe it or not Quake2 is alive and kicking... and its engine is featuring some of the very best open-source games!

For those who might have missed it: AlienArena 7.45 has been released recently and the release makes an already solid game even more awesome ;)

Further more the UFO:AI team is making some great progress after their highly acclaimed 2.3 release two months ago. Besides a a lot smaller changes, various new sounds have been added since then and the rockets got a nice new explosion effect:

Kaaaboom!

Oh and maybe this is of interest for some of you (personally I never really understood the need for it though): War§ow can now be played in a browser window via a Firefox plugin! Check out their development blog for more details.

Yet another 3D adventure game

A rather interesting Project I was unaware of until recently is Ya3Dag. It has quite a lot of rather unique features not found in any of the other Quake2 engine enhancements, like a in-game level editor (!), advanced terrain rendering, day and night cycles and maybe most interestingly a full Bullet physics integration! The developer of AlienArena showed some interest in the latter already, and I think the level editor and the day and night cycles would make a perfect fit for the Ufo:AI game!

Screenshot from Ya3Dag

Check out more screenshots and some videos here!

But lets talk about the actual game. Ya3Dag is aiming to become a single player adventure game (engine) where you play a poor legless pirate ;) It is already playable to a certain extent, but currently there is only a Windows version available (it works well with WINE though).

I quickly send an email to the developer to ask him about this and some other things regarding the media license and future development: Currently he does not have any plans for porting the game to other platforms, but he is open to other contributors. So, if some people are interested in collaboration it might make sense to set up a proper source repository and such (e.g. a sf.net site). Furthermore he does have plans about replacing all artworks with really free/FOSS ones (Yay!), but currently the project is still far from reaching this goal.

Overdose is looking for help

Overdose was a more controversial title in the past (un-free media and plans to keep the code closed), but at least the source code is available now (or at least should be soon *scratches head* as I was unable to actually locate a download link) and IMHO it is the most advanced Quake2 based engine by the looks:

Overdose tech-demo part 3

Recently they have put out a call for help (especially for artists) so maybe you feel like contributing to a really ambitious project? They specifically state that you don't need to be perfect in modeling etc... someone with a good base knowledge and willingness to improve is very welcome! Check out their FAQ if you want to know more about the project.

A small treat at the end!

Ok this is something I just happened to stumble across in the Overdose forum. It's a pretty young project called "Axis Revenge" (name subject to change) currently working with the Xreal Quake3 Engine, but due to various problems with it might change to the Overdose engine (or the UDK, nooooo :( ).

Awesome player model WIP

The rest of the project description sounds awesome too: Alternative history (after WW2) and game-play similar to Wolfenstein: Enemy Territory? Sign me up! But check out their website, and this thread for more awesome pictures! Oh and did I mention that they are looking for help too?
