Wasn't I working on some drag racing game? I decided to play around with camera angles and such. So I created a full isometric 3d view just to try it out for giggles. Now I am knee deep into shadow mapping algorithms and environmental mapping. I am now thinking this might be the perfect perspective for a zombie game I was thinking about earlier. This kind of view might also be better for spectating races or something...
I guess me working now full time I dont feel like I am obligated to finish things in order. I wanna screw around with cameras and a few opengl effects. I might even dabble into glsl.
I still want to get working on redoing the entire car simulation + tire physics, but I guess that will have to wait a bit.
If you haven't already done so, check out the Diablo 3 gameplay video for inspiration - I think they've done a cracking job of handling a big sprawling environment with an isometric perspective.
