All the systems have their great games, which makes it hard to choose... lol maybe they should all work in a combined effort to port system-specific games to other systems. Oh well, My brother has an XBox and I have a GCN. Xbox has some really good games - Halo, Splinter Cell(now coming for GCN). But the gamecube has some good games too like the new Zelda (I still need to get that aghhh) and Metroid Prime, Super Smash Bros. Melee is a classic.
If you have the money, it'd be a good to buy possibly 2 of the 3 systems. Don't forget PS2 - it rocks
