Since this gen is wrapping up, I really wanna take one last look at this past battle, just as the dust settles.

Today's Topic --> Games

I always hear how the PS2 has the most games and is apparently the best system because of that, but last time I checked the GC had over 400 games, more than I could ever hope to play...so I'd say it's better to look at quality, not quantity, since large libraries is something all these consoles now have.

Racing Games
I'm not much for racing games, but here goes. The GC had some exclusives, like F-Zero and Mario Kart, but all the notable others on the GC, like Need For Speed, were available on the other systems as well. The Xbox did have the Project Gotham Racing, but I don't feel that's enough to compete with the ever popular, and exclusive, PS2 racing series, namely, Gran Turismo.
Winner: PS2
-------------------------
First Person Shooters
GC and PS2 both had a bunch of generic 3rd party FPS's, like the 007 series and Timesplitters, but only Xbox had Halo, Doom, Half-Life 2, and Counter Strike. All in all, this one's a no brainer for me.
Winner: XBOX
-------------------------
RPG's
This is a tough one. Sure the PS2 had the whole Final Fantasy series, not to mention some other noteworthy titles, but then again, the GC had some great Namco-made RPG's, Tales of Symphonia, Baten Kaitos, Baten Kaitos Origins (soon), and Final Fantasy Crystal Chronicles by Square-Enix as well. The Xbox may not have had a lot of RPG's, but it did have both Kotor and Kotor 2.
Winner: 3-way tie
-------------------------
Various Exclusives
PS2 had God of War and such, but I don't think it had anything close to the Halo series on the Xbox, in terms of popularity. Now, the Halo series is great, but that's just one big hit franchise. Take the GC's must have exclusives: Metroid Prime 1, Metroid Prime 2, Zelda: Wind Waker, Zelda: Twilight Princess, Smash Bros. Melee, Rogue Leader, Mario Kart, and Resident Evil 4, and it's really no contest.
Winner: GameCube

-------------------------
Overall
This really depends on what you like of course. If you only want FPS's, then the GameCube isn't all that great. If you love Final Fantasy, the Xbox isn't your first choice, and if you love Nintendo franchises like Zelda and Metroid, among others, then the PS2 isn't all that attractive.
My Personal Preference: GameCube, then Xbox, then PS2.
