I know it's games played, but to do something different, I'll only count games I own.
Okay, so two games. An Xbox 360 game named Def Jam: Icon. It's like a rap, fighting game where you can use combos with the environment and stuff. I don't like rap or fighting games (except Smash Bros) so I don't know why the hell I bought that game. The controls made no sense, the music sucked, the graphics were really grim, and the environment attacks were really hard to execute. Oh, and the game was impossibly difficult. The achievements, particularly. Since EA shut down the god damn servers for that game I'll never be getting the online achievements ever. So much for perfection ratio.
And Monster Madness: Battle for Suburbia. A kind of interesting game, at first. That got impossibly difficult and almost unbeatable. With horrible graphics, plot and overall boring presentation. It just got really tiring. These are two games in my collection that I haven't touched in years, and when I do, they only serve to frustrate. me.
