I never liked GTA that much. It's plagued my horrible camera controls (the PS3 version of GTA IV had the camera sluggishly follow the car and the camera wasn't too great anyway), and controls just feel generally bad. It's a pretty bad flaw in an action game.
I never liked Halo. To be specific, I'm talking about the first game. I've tried it several times yet I've never got past the third level because it's just boring. The first two levels... Ngh, I hate them. They're so boring in every way imaginable. After the third level didn't feel much different judging by its beginning, I just quit. No use trying to play a game that's so boring and doesn't seem to get better. Level design was bland and I didn't really like the gameplay either. Maybe I should've been a console-only gamer and should have played it on the Xbox to enjoy it... But really, no thanks!
Hmm, what else. Well, I liked Final Fantasy XIII despite its flaws, probably because I enjoyed the battle system which is something that many criticize. True, there's the mashing X thing but then there's always the constant thinking of which paradigm to use - and building those paradigms, too. Makes it much more tactical and I like it. Also, many end-game battles weren't simply mashing X and even before that, there was the occassional time you had to figure out something that wasn't simply mashing X. I felt like it was a nice system.
I'm sure there's much else too but I can't really come up with anything right now. Maybe I'll post here again later. :p
