Apparently I lived in a weird gaming bubble. From what I read online the PS2 was the God console and destroyed everything. But there wasn't much talk about the PS2 in my high school. And other than Halo there was zero talk of the Xbox.
There were the kids with the Xbox, usually stoner pot heads; and there were kids with the PS2, usually the jock/non gamer types. But everyone that was into games had a Gamecube (and a PC). And we all loved it.
Looking back on it, almost 2 decades later, you can pick the console apart, but that's not really fair to do without living through it.
The load times were almost cartridge fast (PS2 took minutes to save and load in some games).
The graphics were competitive, and in a lot of cases superior.
The WWE games and Smash and split screen shooters ruled.
The 2 exclusive Zelda's were amazing, and the extra discs let you play every other Zelda game from NES-N64.
Nintendo gave us Mario Kart, Mario Golf, Mario Soccer, Mario Sunshine, Animal Crossing, Luigi's Mansion, Pikmin, Metroid Prime.
Capcom put out 6 Resident Evil games on it alone. Ubisoft had great versions of Tom Clancy games. Sega ported Skies of Arcadia and Sonic Adventures. Lucas did great Star Wars games. EA did all of the Need for Speeds, Call of Duty's, Medal of Honor's, those great Lord of the Rings games, SSX Tricky, NBA Street.
Not sure what you guys were playing in 2001-2005, but if you weren't any of that you were missing out big time.
