XBOX!!! i have one...it is plainy the most powerful console made yet...even though it doesnt have a lot of games...even though the nintendo was the most revolutionary game console made yet.
i'd have to go with x-box cuz i got one and im into most of it's games like Halo,DOA,well yeah some others..plus it plays dvd's and music..well, i think others do to but i prolly just like it best cuz i have it.
I have a Gamecube,Playstation 2 and a X-Box but i would choose my XBox as the graphics are a lot better and the fact that you do not need a memory card
Xbox by far, unlike the other two the pad isn't small, i don't know if you've tryied playing a PS2 or a GC after playing an Xbox but it likes going back 15 years to retro consoles.
