after 2002, things started to drop off rather quickly. sega sports as a whole were done on the gamecube. burnout 3 and revenge, baldur's gate dark alliance ii, 187: ride or die, 25 to life, 50 cent, aeon flux, alter echo, area 51, arctic thunder, arena football, the bard's tale, battlefield 2, black, blitz: the league, bloodrayne 2, broken sword: the sleeping dragon, brothers in arms: road to hill 30, brothers in arms: earned in blood, cold fear, conflict: global terror, conflict: vietnam, darkwatch, dead to rights ii, dynasty warriors 3, dynasty warriors 4, dynasty warriors 5, evil dead: a fistful of boomstick, evil dead: regeneration, fatal frame, fatal frame ii, onimusha, godzilla: save the earth, guilty gear isuka, heroes of the pacific, indiana jones & the emperor's tomb, indigo prophecy, the king of fighters: maximum impact, mafia, marvel vs. capcom 2, max payne, max payne 2, mercenaries, myst iii, psychonauts, psi-ops, return to castle wolfenstein, silent hill 2, silent hill 4, star wars: battlefront, star wars: battlefront ii, and state of emergency, among others, found their way to the xbox and ps2 but not the gamecube.
and if it the system got a multiplatform game, oftentimes it came weeks or months after the ps2/xb versions. third-party on the gamecube was pretty piss-poor. the wii was better. yeah it didn't get all the multiplatform stuff either, but it had its own exclusives and a lot of other games that appealed to a different demographic.
