I hate Dragon Age, mostly because of its blandness, and the fact that you can't stash loot unless you pay for DLC. Fuck you, BW.
Tales Of Symphonia, because the characters spew retardedness out of their mouths like machine guns.
I found GTA4 seriously annoying. Crap driving, stupid dating bullshit, and that motherfucking cell phone. What were they thinking?
Oblivion, as well as Fallout 3. I really can't for the life of me figure out why they're so popular. The levelling in Oblivion is so dumb it's not even funny, and Fallout 3 doesn't even have a millionth of the depth and quality of writing of the first two.
These are not games I find just overrrated. These are games I've paid money for and hate hate hate!
