Games that most people like but you don't.

[Bodhesatva]

Pretty much anything single player and/or story driven: Metal Gear Solid, Final Fantasy, Bioshock, other RPGs, etc.

Single player games are, in general, significantly easier than mastering a multiplayer game like Counter Strike: in fact, people are still mastering Counter Strike to this day. By contrast, I can "master" Bioshock in about a week. As a "hardcore" gamer, I care a great deal about challenge and complexity of gameplay.

I wouldn't mind story driven games, except I still haven't played one I actually felt had a good story. My last attempt was MGS4, and I thought the story was so hilariously bad. Genetic super spies fighting giant mech robots: that's deep stuff!

Everyone else is welcome to their own opinion, of course.
