Wow, this thing has some great potential.
I invited you (or something) on MSN so you know it's me. I'd very much like to get involved in this. This is almost what I've been searching for for a while.
I might model some miscellaneous stuff that you haven't mentioned, so I doubt you'll have modeled it yet. Stay tuned.
But mostly, for the game development, I'd consider looking into Unity 3D. You'd have to rig and animate models in MilkShape, but that's a small price to pay for an awesome game engine.
Just a suggestion, of course.
I really like your ideas, Arik, and I hope I can get some time, stop being lazy and start using Anim8or again!
See ya 'round
