World of Warcraft: warcraft has very, VERY uninvolved combat, to the point i find myself avoiding it altogether because it bores me, it would greatly improve the game if it used the same combat system as Dungeons And Dragons: Online.
Oblivion: REALLY long loading screens, i actually chewed the rubber from my anologue sticks in boredome, also, the game would be much better to me if it had the same kind of blood and gore as Fallout 3. Just sayin'.
Saints Row 2: More voices for the main character, there are only 3 options, NONE of them are the same voice as the character from the first game.
On that note, why the hell is the main character such a total annoying prick? the four--FOUR--lines of dialogue from the first game were funnier and better acted than any number of one liners from the second game.
Legend of Zelda, Wind Waker: The HOURS long triforce hunting quest about halfway through the game.
Also, Tingle, just, Tingle.
Legend of Zelda, Ocarina of Time: I never actually finished either Ocarina of Time or Majora's Mask, know why?
The fucking water dungeons.
