I'm announcing a homebrew project my group is working on called NARG (Not Another Roleplaying Game). We don't have much completed as of now, but we've put together an game engine proof of concept which can be found at our website http://trege.homelinux.net/narg/, along with more details about the game.
We're looking for user feedback right now. We're also looking for some people to join the team and help with non-programming development. Again, more details available on our site.
Note: We've provided a 2.0 format package (as well as 1.5), but we're unable to test if it works, as nobody we know has a 2.0 firmware.
