Yeah. The fact that Lua has existed for a while and has a fairly big 
user base is a definite advantage.

One of the issues is the fact that Lua numerial format is double 
precision floats. This isn't a problem on PC and DC. But PS2 is 
optimized for single precision and often uses software emulation for 
double precision. So i'll have to see if there is a way to get Lua to 
use single precision to avoid arithmetic slowdowns on PS2.
