I just had a wacky idea - If Asteroids were a special version of a ship (so that they wern't static, but rather a floating entity), so when you ram one with a huge ship you can actually displace it. it would kinda make asteroids more asteroidy and less of a "unmoving space anchor"
I don't know what kinda of effect this has on performance though, i wouldnt have thought it would be that much...
