Jumper (If you've ever played this, you'll know why)
Crash of the Titans (Completely bastardized what the Crash Bandicoot games were about)
Tak and the power of JuJu. (Really, this one sucks so badly that I can't even express it)
Big Mutha Truckers (Drive from point A to point B within the time limit over and over and over and over again)
Halo 3 (The sheer amount of fanboys this game possesses makes me ashamed to have bought it)
Two Worlds (I don't even know how to express this one)
Fable 2 (They COMPLETELY fucked up the magic system for me. Fuck that.)
Farcry 2 (They got rid of the feral powers which PISSED ME OFF and the AI is fucking Godlike when you're trying to be stealthy. They can see you through a fucking HILL for fuck sakes)
Assassin's Creed (There was no assassin element in this game for me. Each damn target SAW YOU AND FOUGHT YOU! The only people you could actually assassinate were civilians and guards)
Every Pokemon game to come out after Red, Blue, Yellow and Pokemon Stadium. (It's the same fucking thing over and over again)
Some Yugioh! games on the PS2. (Really, the AI is fucking cheap as hell)
All sports games. (The fucking concept fails. Playing sports on a console in your living room and on your couch defeats the entire purpose of sports.
Over G-Fighters (UGH! The person who made this should be burned alive in a vat of acid)
Dead to Rights 2 (COMPLETELY FUCKED DEAD TO RIGHTS UP! I couldn't even play 1 properly after I played that massive pile of festering shit!)
F.E.A.R 1 and 2 (NOT. FUCKING. SCARY.)
Dead Space (NOT. FUCKING. SCARY.)
Edit: I just finished THe Legend of Zelda: Majora's Mask. It was fun, but the entire "After 3 days you have to restart almost everything you've done and go back to the start of the fucking game lolololol" bullshit. A few times I was right at a boss fight, but the fucking time limit was up and I had to restart the entire fucking dungeon all over again.
Edit 2: How could I possibly forget about GTAIV? Realism like that does not belong in a game. I've never, NEVER seen a person fall 6 feet and die. Injured, yes, but not DIE.
