Which type of multiplayer do you prefer?
Co-Op games/modes where you work together?
Single VS games/modes where you work against each other?
Team VS games/modes where you have to work together better than the other team does?

Single player is not a topic for discussion in this thread.

I find a lot of my favourite multiplayer games are co-op. (Portal 2, Sanctum 2) I like some team games but that varies widely depending on who my team is. I don't like VS very much or MMOs (as I am not good at them)

Racing games are an exception for vs though but I do get bored after a few games unlike Co-Ops
