Mostly stuff in fighting games aggravates me. Like when you get someone down to like 1% health and then suddenly everything goes in their favor. I probably just suck at the game but it pisses me off. ~___~
That and playing against my friend in 2k12 when he's using the Thunder. Durant can stick lots three's with defenders directly in his face.
And then when I was ten, ON EASTER, I saved my FF IX game at the last possible save point in Memoria. And when I went to play the next day it went corrupt.
