Physics. Because you wanted to include a physics engine. If you don't 
use a physics engine, you don't have that option.

That'd be good to find out :-)

Usually, it's the case that quality has to cost, because there is much 
less competition the more specialization and higher quality you want. 
The cheap generic crap is just that, cheap. That doesn't mean that 
everything that's expensive is good, of course, but it does mean that 
it's generally hard to be consistently good without being expensive.

Middleware seems to start at the $250 range (old Torque, C4 engine, 
etc), take a leap to the $5k-$10k+ range (Granny, FMOD, etc), take 
another leap to the $50k range (physics packages etc), and then have a 
top strata at $150k+ (full engines, scene graphs, integrated editors, 
etc). Within that range, I wouldn't think endorphin is entirely out of 
reason.
