Yeah, Wii is pretty cool, but this time around with the new systems I decided to only get one instead of all three. Well, that plus I have kids now and my free time is taking up a lot with this site.
But, I do have the 360. Got it for Xmas. An unbelievable system. I used to be a loyal Playstation owner until I got an Xbox....it is definitely a more adult oriented system, and the Xbox exclusive games like Halo, Gears of War, and others are incredible. What I love about my 360, is I can download movies off the net, and then stream them from my computer to the 360 and play them on my TV in virtually perfect picture. This made my wife very happy upon learning this.
PS3 is awesome too, from what I have seen, but I don't believe it is worth the $500-600 pricetag, especially when you consider the 360 software library being almost twice the size. Plus, the exclusive games on Xbox are better, at least to me. The only game I will miss on PS3 is the Metal Gear series, but that always gets rolled over to the other systems a few months later anyway, so I'll still be able to get it on 360 at some point. Can't say the same for games like Halo. They are only on 360 and never go anywhere else.
BTW, I almost got a Wii as well because I wanted to play that new Zelda game that every mag is raving about, but found out the Gamecube version was exactly the same (minus the use of the nanchuck controller on the Wii). So got the Gamecube version. Haven't played it yet, but hope to crack it open soon (playing Halo 2 on-line and Gears of War right now when I have free time).
