I have outed myself previously as not a big Minecraft fan, so take everything in this post with a grain of salt (as I obviously don't really understand that genre).
Seemingly made by people not happy with the recent commercialization of Ace of Spades, it's an all FOSS remake, those early development you can follow here (or on their Github page).
Now maybe the graphics are lacking on purpose (see disclaimer above), but I couldn't help to think: why for f***'s sake did they have to reinvent the wheel with their own engine instead of using for example Terasology:
Ahh well, at least it made me aware that Terasology is still very much under development, and with its focus on DungeonKeeper & Dwarf-Fortress elements, it might actually become a game I would play (and doesn't make my eyes bleed :p ).
Speaking of which... the guy behind AgentKeeper released yet another nice video and graphics are constantly further improved as seen here.
While Blender3D is one of the premier FOSS projects out there, its integral part the Blender Game Engine (BGE) is often belittled as not a serious game engine.
While the criticism is certainly not completely unfounded and the integration of limited "non-programming" game code creation (via logic bricks) gives it a bit of a "RPG maker" image, it really is a quite interesting platform to work on it seems. Ok, probably as of now the BGE is really more of a rapid game prototyping engine, but previous experience during the Yo, Frankie! project has actually shown that at least compared to some other well known FOSS engines, it is a serious contender (that Blender Foundation project originally started on Crystal Space, and after many problems was implemented in the BGE in a few weeks only).
So what makes it so interesting? Well for one there is the full integration with a creation tool (obviously Blender3D) so that getting your content into the game is only a matter of making it. No exporters or anything needed... it just works. Then of course there is the fully scriptability via Python, also integrated tightly. Basically you never have to exit Blender, and testing your game can be done right in the editor with one click (no compiling etc. necessary). Oh and did I mention the great physics capabilities via Bullet, also build right in?
In addition your created game will be immediately available on any platform the Blender Game player has been ported (all major desktop operating systems, with an Android port under development and a browser plugin, too). In addition you can choose to publish your game as a single .blend file, giving the users a direct access to all the source files of the game; a wet dream of any true FOSS game developer! The tight integration with the GPLed Blender Player, has been a major source of discontent with the predominately propitiatory game developing users of the BGE however. Thus there now exists also a few options to encrypt your game and/or run it on an external engine that can be kept close source (but I will not go further into that here).
You can find a lot of (sometimes really awesome looking: 1, 2, 3) game projects on the Blenderartists.org forum. Now as I said, most of it is sadly closed source with propitiatory artworks, but I also have the feeling that some simply don't know or care about the legal implications of their "freeware" game (which sadly shows that even many people who use a great FOSS tool, mostly care about the "free as in beer" aspect of it).
One of the more interesting projects right now (which might or might not become a full FOSS game) can be seen in this video:
It shows the most recent work by Martinesh, who is basically BGE's resident game art guru. Two years ago we already featured previous awesome work by him, but sadly that Air Race project is by now canceled. What he is now working on is however rather a show-case for the really nice new graphical features in the BGE which he and others are developing in the so called "candy" development branch (on his blog there are also more details and nice videos from some time ago).
Another cool recent project it the rewrite of the the logic bricks visual programming idea via nodal logic blocks called Hive.
While not completely integrated into Blender yet, you can already try it via an external editor (the created python code works fine inside Blender). There are also some tutorials and a documentation for it. Since my programming skills also lack somewhat, I find that an interesting tool... however most likely it is rather a nice way to do some level scripting, than actually programming the real guts of a game with it.
I mentioned this nice new project that appeared on our forums some time ago already, and while the promised source-code isn't available as of yet, a new and quite good looking video was recently posted:
Now as you can see, it shares quite a lot of graphics with OpenDungeons, which is not completely dead either, but there is at least some discussion to "jump ship" as AgentKeeper is progressing much quicker (with it being a University supported project). You can follow AgentKeepers progress here if you fancy some nice dungeon management simulator ;)
Well at least that could be fun... anyways, as they explain in their last two weekly updates (1,2), their Demon Engine has seen quite a few graphical updated an bug fixes lately. Furthermore they highlighted an upcoming major change in game-play compared to Tremulous, as Unvanquished will be using a real resource gathering system.
Also a cool new screen comes from the "Modern Warfare" mod for 0 A.D.:
Tanks in 0 A.D.
In their WIP thread on the 0 A.D. forums they have also confirmed that the mod will be "open source" however did not specify this further. It also seems like they have plenty of good artists, but are lacking a bit on the coding side. So if you know your way around Javascript and XML hacking, give them a hand (and secretly lobby for a full FOSS release ;) ).
Just released today, there is a new version (1.9) for Stunt Rally:
Stunt Rally 1.9
It has a few nice new features, but probably the greatest update is a major change in the car handling physics, including an "easy" mode for those of us not wishing to practice for a career as a professional rally driver ;) and the guys would like feedback in the SR forum so let them know what you think.
A big collection of (partially quite crazy) screens can be found here.
Another great release that surfaced just today is Warzone2100 version 3.1.0. It cumulates all the changes made during the last 2.5 years, however if you tested the RCs already then there isn't too much new. Most notably they mention the new and fully fixed netcode, so that "out of sync" is a thing of the past (unless you have a crappy net connection like me :( ).
Hat tip to forum member TheLastProject who posted about a promotional video for a proof of concept research project called 'IllumiRoom'. The main game shown is Red Eclipse, but SuperTuxKart also briefly appears (implicitly as the game played by a girl!) around the 0:48-50 mark.
I doubt they were actually showing an Xbox as I'm unaware of either Red Eclipse or SuperTuxKart being able to run on one.
I find it fascinating that 2 FOSS games would appear this way. Either this is an indication of red tape avoidance (no permission required for GPL games) or a cultural shift within Microsoft - or perhaps I'm just reading too much into it.
It certainly adds some validation to the games themselves, indicating they are impressive enough to feature as part of a video by one of the world's foremost technology companies. So hats off to the developers of both projects and also the projects that enabled them (CubeSauerbraten, TuxKart) - I like it that both games are good examples of open source in action.
Just a quick heads up. GarageGames is currently raising money to port their recently open sourced Torque3D engine to Linux, including editing tools. Here's a link to their IndieGogo page. They're using a fixed funding campaign, so you don't have to worry about losing your money if they don't reach their goal.
We could use a capable 3D engine with mature, commercial quality editing tools on Linux (yes, there are other FOSS engines that run on Linux, but what we don't have is something that comes close to Unity at the moment in terms of ease of use) -- not to mention the fact that this would open the door for people to port a lot of existing games.
If you'd like to see this happen, stop by their IndieGogo page and help them out.
