X-Box, plain and simple. PS2 is an outdated console that SHOULD BE DEAD, BUT NOOOOOOOOOOOOOO, it has to still survive. The Dreamcast is MUCH better than it for crying out loud!
Of corse you can always compare the specs. To make a long story short, PS2 is the WEAKEST console. Its graphics are quit sub-par when compared to Gamecube and X-Box
Personly, I suggest getting a Gamecube, because Nintendo have been in the business LONGER than Microsoft and Sony, so you know that you'd be getting a good system. Add in SOME OF THE BEST RPGS, MUCH BETTER THEN THAT OVERRATED FINAL FANTASY X JUNK, and Gamecube is the best for RPGs. X-Box has Halo and Halo 2, which are excelent FPS games
So in short, PS2 is a weak system which should have died AGES ago. However, they still keep going for some reason. So save yourself the disappointment, get a X-Box or Gamecube. X-Box has HEAPS of online stuff to keep you occupied, and it also has that Fable game which I've heard about. And of corse, Gamecube just rocks. Don't give me any of that "OMG, GAMECUBE IS TEH KIDDY11!!!!!!!11!" trash, cause I doubt anyone who's actualy played the Gamecube ever says that
