I'm also doing a 3d project, but its not a sonic 3d game (I don't know if I can make a good one), its a Flight simulator/Shoot'em up style game.
I'm making a game using the idea from sonic adventure's Sky Chase level but making more levels, enemies and bosses..
The gameplay will be like After Burner Game (the SA gameplay isn't very good).
now I'm working in the game logic system, the graphic engine need lots of work, because I think that the game-logic is far more important.. (the camera is 90% finished).. to maintain a very good gameplay I need a lot of works, but I have time.
about the models... not everyone have textures yet, but at least they have their one unrwap image. I have two differents kind of models, in low-res and in high-res.. the low-res will be used in the DS version, and the high-res in the PC version.

(
this is not an in-game screenshot, its a pre-render from a 3d editor)
the real graphic engine don't show the textures and the lighting very well... its work in progress yet.
I making the engine using openGL, but I wanted to port to DirectX too (I'm also doing a DS version. I have lot of optimized and reduced models for the handheld version), but while I don't finish the gameplay, I won't continue with the graphic engine.
