Most obviously, the Wii is simply not a powerful-enough system to handle GTA4. Its lackluster graphics abilities are just a shade above that of the Gamecube, and it wouldn’t be able to handle the huge Liberty City without a loading period on every street corner….it simply can’t compete with the 360 or the PS3 in that area.

Secondly, the Wii player is not usually the kind of person who likes Grand Theft Auto. Most Wii players are older (as in, 40+) gamers who are just getting started, or younger (13-) who could never get a hold of anything rated M. GTA4 simply would not sell well if made for the Wii.
