To be honest, I think that they're using the Wii port as the basis for the PC version; the requirements are very low
compared to any other 360/PS3-based PC ports (Particularly the requirement of a 1.6 GHz CPU; that just meets
KotOR I's standards, and that lacks a true physics system). Same goes for the supported GPUs; both the 9800
and 6800 are five-year-old cards.
