My list:
1. WRPGs:
They are so boring and always just the same. Same story, same boring cliches. Can't stand them.
2. FPSs
I don't understand how some people could actually enjoy this genre. All you do is run and shoot some lame bad guy/other player online. Boring.
3. Mini games
These are so shallow and boring. Can't stand them at all.
Bet with Dr.A.Peter.Nintendo that Super Mario Galaxy 2 won't sell 15 million copies up to six months after it's release, the winner will get Avatar control for a week and signature control for a month.
