I'm coming back to you after a (long) while...
As some of you may have seen, Plith is now a complete game and is giving me some satisfactions. I was so happy of this first experiment, that I decided to start with a new one - Yorg - a Panda3D racing game.
The project is going quite well, and I think that a playable demo will be available soon.
Regarding technical details, physics is managed by Bullet, while our artist chose to use blender for 3D modelling and GIMP for texturing; all the audio has been taken from Creative Common's world.
Sources are all available from the project page, while our blog (far more divulgative) is here.
Just to have an idea of what we're working on, here are a couple of screenshots:
and a quick ingame video:
I really hope to have your feedback, so... come and visit us!
