Of course, when I say new, I mean new to me. New to me means, generally, a bit off the radar in the Free Software game community. So, with the post title qualified, let's start...
Top10 is a realistic kart racing game for Windows and Linux. It reminds me of Karting Race, which is fairly inevitable since they are both kart racing simulations, but Top10 is GPL (yay!) whereas Karting Race is freeware (not-so-yay!) so it already has that going for it over Karting Race. (See, I believe that being open source is a significant strength for a freely-available game.) It's quite playable already although still undergoing heavy development. Less words, more video:
Opposite Lock is a racing game for J2ME platforms, originally written for mobile phones. The author has released the engine under a GPL license with 3 free tracks, and is planning to release the game tools including a tile-based track editor, as open source too, and eventually his game tracks under a CC license. It looks like a really fun game, is a complete game, and could be great for the GP2X or maybe OLPC or similar platforms. It's a bit like the original MarioKart but with cars. See the video:
Thanks to Andrew for bringing that one up in the forums.
Teewars is a cute 2D deathmatch game. It's a bit of a cross between something like Quake and Metal Blob Solid. It's very similar in scope to the Liero-style of game, an open source version being OpenLieroX. It looks full of potential although it's probably going to be multiplayer only. However, there is a caveat. It's under a rather strange open source license.
How am I doing? That's 3 so far. I've got one more. OpenClou! is an effort to keep the genre of the burglary simulations alive. It's 3D, it's open source, beyond that and the following video, and the obvious ethical debate on whether we should promote or glorify theft, I can't really say much more!
That's it for today. Very video laden! :-)
