I have difficulties playing SP games for long. JK is even worse
I do like adventure games, but more in idea than in actual game play. I guess I'm more of a adventure maker than an adventure player. I prefer game-mastering to playing in most cases. I liked torment a lot, but didn't even get half through the story. Watched my brother play a bit and thought that it looked awesome. Same with fallout. I think I'm more into the mood and setting than into the stories themselves.
I do like coop-play. Especially coop vs coop games. Starcraft was most fun when you were 2vs2. GAmes are generally more fun when they have a social aspect. Together or against.
