Screw the Wii and PS3, get a X-box 360 instead
Ok, Ok, stop throwing rocks and tomatoes
Seriously, there's a PS3 for $250 now? I've been very close to getting one, I can count the games I'm interested in on one hand....but it's a cheap blue ray player too. So, why not get a Blueray that just happens to also play games? I'm going to have to look for that.
The Wii, I have been thining about, there are a LOT more games on it I'd be interested in, but I can get a X-box 360 for less (though I already have one so...) But the controls. Give me a damn pad, I'd love some Mario action, but not if I gotta wave my arms like an idiot (assuming I don't loose interest in the control setup before I get tired of doing it)
Over all, I think the Wii gots a lot of great games, the PS3 is very similar to the 360, and has a grand total of 2 exclusive games I'd be interested in (one with horrid ratings, the other a GTA ripoff)
Like a lot of people said,you'll just get biased oppinions, just make a list of games for each system you think you would like, also, include known games for the next year or so, and pick the systemthat you are more interested in for games. If you already have a 360, there's not much you'll miss beyond bluray if you don't get a PS3, if you don't, the PS3 provides more traditional gameplay.
