$342 to play x2 good games? You'd be better off buying a 3DS or building a decent PC (Steam always has sales). If you are a console gamer I would wait for the next gen console announcement which have already been rumored and will be revealed@E3 2013.
For me the 360 or PS3 and their replacements are the logical choice. But for some (very casual gamers) the idea of wii bowling and such is much less intimidating. I guess I could try and find some easy to play xbox games...but the learning curve just seems so much shorter on the Wii. I'm just not sure what my wife and I would ever play together on the 360 though.
