Guitar Hero and Rock Band. I get no enjoyment out of pressing buttons at timed intervals. Or if I do, it gets old very quickly.
The music is good, but ruined by the repeated tapping of plastic buttons along with the strumming of that thing on the guitar.
Also, anything from the Atari era which people gush over and say "ZOMG BEST GAME OF FOREVERZ". Pac-Man, Tetris. They're not bad games, and for their time, they were phenomenal. But now...seriously, they're outdated, one-dimensional and dull.
