Good singleplayer games without any story?

Players usually want a good story in their games. I can enjoy a good story too, but sometimes I just want to get going and do stuff without listening to several minutes of dialog in-between action.

Do you know any games where there's no story (or very minimal/skippable one), and the game mechanics alone carry the game?

EDIT: Thank you all for the suggestions. There are some that I've never heard of and look very interesting. Will definitely pick some of them up.
