Well, considering how early it is in the Wii's life, it's rather unfair to say it's going to die, or Nintendo still has a "kiddie" image. In fact the next few months we're going to see some pretty nice releases, as well as some of the "sandbox" games so-called mature gamers wanted so badly.
I'm not saying I'll get it, but come on Manhunt II on the Wii? That's nuts.
