I'd like to make a simple 2d car crashing game, where the player would drive his car into moving traffic and try to cause as much damage as possible in each level (some Burnout games had a mode like this).
The physics part of the game is the most important, I can worry about graphics later. Would engine like emini or box2d work for this kind of game? Would Android devices have enough power to handle this? For example if there were about 20 cars colliding, along with some buildings, it would be nice if I could get 20 fps.
