The SuperTuxKart team is looking at another release in the near future with an improved UI and lots of bug fixes.
And finally a new game! Stephen Carlyle-Smith wrote to me to introduce Nuclear Graveyard:
I'd just like to tell you about a new free game that I've written which hopefully you will mention on your Freegamer blog. It's a fork of the old Laser Squad 3D code, and it's called Nuclear Graveyard. It's a persistent 3D squad-based realtime strategy game. Basically, players can connect and control the units, and either play against each other or against the CPU. The homepage is at http://ngrave.pbwiki.com/. At the moment the graphics are a bit basic, as I'm no 3D artist, but the game is completely finished and playable. As it's new, its community is very small, but I'm hoping it will get bigger as people discover it.
I could not find a link for Laser Squad 3D.
