Hi, I want to play some games on my Intel HD 2000 notebook with my friend. What are the best games to play on one keyboard? (We already play SuperTuxKart)

That is awesome game, but by "friend" I mean my girlfriend. And I do not think, that playing strategic games with a girl is a wise idea.

I think it is very similar to Worms, but it can go.
