I've written a small demo showing off a bulletml script... The game will basically be a typical shmup with a few gameplay twists (haven't figured them all out yet...).
What I want is a 3d background like in the game Ikaruga... Question is should I make the game 3D from the start, or continue using accelerated 2D and try and utilize 3D only for the background?
If I go 3D all the way, which cross-platform engine would you suggest?
Also, where's a good place to host my files/project?
