i've got both machines and truth be told, i do prefer the ps2.
My xbox is with matrix and i've got tons of homebrew software...which is goddamn nice to have! Megadrive emulator etc!
Although it's just too much like my pc to get excited about.
Although i have to say, the shenmue series will always have a place in my heart
Simply amazing!
Ps2 has better games though! I bought my xbox the day of release and since finishing the release games, other than panzer dragoon orta there aint anything else I wanna play.
