GTA on the Wii?
I don't know. It's just that the Wiimote is universal, TOO universal for a GTA game. Like what some members posted in this topic, the Wii's pad is just too sensitive. I mean, if I'm, for example, walking in a pedestrian lane and someone called me, my hands would drop the Wiimote. If I had very low health, and was on a mission, and was hit by a car because the Wiimote forced the AI to move to the nearby road, that's annoying. WaW is a big fat example.
But let's just say that Rockstar can avoid these.
