This isn't the first post I've seen with people whining about how the Wii doesn't have "adult-oriented" games. If you're not satisfied with your Wii, go buy a different system. If you want more adult titles, why would you invest in the Wii in the first place?
And the Wii-Mote isn't a gimmick, in my opinion. I have a PS3, as well...and while it has great potential, and a couple games I'm looking forward to (FFXIII!), I have to say that the Sixxaxis (or however you spell it) is a gimmick. It's wireless and all, but did they really need to incorporate motion-sensing technology into the controller if it's hardly utilized, and when it is, it isn't very enjoyable?
