There are many factors that can go into getting the game system of your choice. For one, it depends on what kind of games that you like. For RPGs, the PS2 is clearly dominant with Xenosaga, Kingdom Hearts, FFX and FFX-2, Arc the Lad, .hack series, Grandia 2, and Final Fantasy XI. GameCube has Skies of Arcadia Legends, Phantasy Star Online Episodes I and II, Lost Kingdoms 1 and 2, and the soon to come out Final Fantasy Crystal Chronicles. XBOX has even smaller library but all of the games rae some of the best RPGs ever wtih Elder Scrolls III: Morrowind, Star Wars: Knights of the Old Republic, and the 2004 release Fable. PS2 wins in this category. For sports games, the XBOX and PS2 are dominant. All 3 systems have the EA Sports games but only PS2 and XBOX get them online. Microsoft though, has its own line of games that are all compatible online like NFL Fever, Top Spin, Amped, and more. XBOX comes out on top in this category. For shooters, XBOX probably is on top. While all systems get the mediocre Bond games, XBOX has obtained Halo, one of the best FPS's out there, and don't forget, Valve has said that they might bring Half-Life 2 to the XBOX. PS2 has Red Faction and a few others, but not very strong. I don't think GameCube has anything other than Bond. The PS2 is dominant in the racing games category, it's main titles being Midnight Club 2, Gran Turismo 3, four is coming out soon, and Need for Speed Underground. MC 2 is for XBOX also while GameCube is left out of this category. The Sega GT game for XBOX was okay and they are making a Sega GT Online game. GameCube does come out on top in the category of platformers and party games. Mario Party is the best one out there and Super Mario Sunshine was a great platformer. The best system for stealth action games is the PS2. With Metal Gear Solid 2 and Metal Gear Solid 3: Snake Eaters on the way, it is dominant. It obtained Splinter Cell, a once XBOX exclusive and leads this category. GameCube surprisingly comes in second with the first Metal Gear Solid game in a remake called Metal Gear Solid: The Twin Snakes. It will contain brand new levels and great graphics.What about fighting games you say? Well, PS2 is again dominant. While all three systems have SC2, PS2 obtains the best with Virtua Fighter 4 and Tekken 4. XBOX next with Dead or Alive 3. Then GameCube with the okay Bloody Roar: Primal Fury. Well, now, which system has the best graphics? Definately the XBOX! Just look at Splinter Cell on the XBOX with the excellent lighting and graphics and compare it to the PS2 and GameCube version. Clearly superior. GameCube places second and PS2 third. The two winners only were superior because they came out a year after the PS2. Another big factors is the controllers. GameCube comes in first, but this is mainly preference. The GC came in first because its controllers are good for small hands. Thats not all, the third-party controllers make it great for large hands. The clencher though is that for $9.99, you can buy a cable that allows you to use PS2 controllers with the GC. Next is PS2, with its overall comfy controllers. Then XBOX, which has way to many buttons and is very big. For small handed people though, get the MicroCon, a great third-party controller. Well, in conclusion, PS2 won most of the categories but the system that you want is really just a matter of preference
