game i'm suprised i hated = halo 3. i'm suprised because it seems like a really good game, but for some unexplicable reason i don't enjoy playing it (and i love sci-fi + FPS games).
i don't understand why so many people were disappointed with gta4.
it lacked the replayability of the average 'sandbox' game, but if you forget about san andreas, it's still a terrific game in it's own right.
imo the number of gta haters are largely players who didn't play the gta games in order. probably starting with vice city/san andreas first. GTA3 is a groundbreaking game, which set the stage for the 'add-ons' to follow. imo GTA4 has set an incredible stage for future true add-ons (lost and the damned was clearly just microsoft's daft idea).
i believe the GTA4 graphics, animation, sound, story, characters, driving physics, player physics, combat mechanics etc are around the highest standard we've seen from any game of current generation. i've completed the story about 5 times, and if i had more time i'd be playing it again.
