I thought this had been mentioned on this forum, but search didn't show up anything.

Anyways, there is a really interesting Torque3D based game currently asking for some funds to update the game from the formerly closed source (years ago) engine to the new MIT licensed one and also go fully FOSS with artworks etc.

Gameplay is quite fun and unique, and you can already try the exsting version (small download due to it's abstract graphics, so no excuse not to try ;) ).

Only 5 days left, but the amount is almost reached, so if you can chip in some dollars.
