My option the PS3 isn't the best conclese, mainly only for HD tv('s), i think the Xbox 360 is best because it has awsome graphics, for both HD and normal TV's. If you've played Assassins Creed, you can notice alot of what im talking about. So games are different, but most games have awsome graphics! Xbox live for the 360, and account creation is good not much dif from orginal in those.
2nd is the PS3, its graphics.. I say... amazing with HD. I've played Assassins Creed for that as well, (with HD of course), its graphics are little better then Xbox 360.
3rd The PC, of course, everyone loves the PC, Mac, windows, lindux (sorry if i miss spelled), some many games to choose from, and alot are FREE! Runescape, Maple story, World of Warcraft (not free but its on of the most best PC games.)
4th Wii, Its fun yay, but the graphics arn't as good as they could be. the Wii remote and nun-chucks are fun, but sometimes can be complicated, and the remotless motion sensor you have to play ontop of ur TV doesn't always catch your moves, which could suck sometimes...
theirs alot more i could do, but im good.
