Wow, lots of replies. Already started checking out a few of these games.

But I decided not to buy starcraft 2 right now. I really wanna play that game, but 60€ is ridiculous for a game coming from one of the hugest companies.

Trine has a multiplayer mode? O.o funny. I have that game sitting around here. Good game. But I never thought about playing it mutliplayer.
haha... I'm still on XP^^

I played Diablo II through with my _girlfriend_. How cool is that?!

I want there to be a little more action than the average browsergame has, so that won't do. But I think I'll try Magicka and maybe C&C. Maybe Titan Quest as well...
