As nice a toy as the Wii is, it's being harmed by the fact that it's being marketed as a 'family friendly' machine, and in terms of Force Unleashed, that's a game that's multiplatform. Meaning the Wii loses out on it.
Apparently, there isn't enough 'strong' games for it, which is why a fair amount of people are returning the machine.
Now, I don't hate the Wii, any more than I hate the PS3 or the Xbox 360. I go where the games go, and if that means I'll have to end up owning all the machines to play the games I want? Sure, I'll do it (Somehow.)
But so far, only two consoles have games I want, and the Wii isn't one of them.
