Well, I have al 3 consoles.
Personally, I like all 3 of them.
I've had my PS2 longer, so I obviously have more games for it.
The games I have for GCN are fine, but not the BEST.
THe 2 XBox games I own are pretty fun, but I haven't done much with the system, since I got it a couple days ago.
Overall.....I'm glad I own all 3
They all have their strengths and weaknesses.
I think this console war will end like the previous one did.
Sony won the last war, and Sony will win this war.
The PS2 outdid both the XBox AND GCN this past christmas season, so I think that says something about it..
Just because its not the most powerful system doesn't mean that it's not the better system overall.
