I'm pretty sure Left 4 Dead has "best coop game" all wrapped up. Nothing artificial only one person or the other can do - but you *need* your friends to survive because they create scenarios that a single person simply can not get out of.
That said, when I bought and then played L4D2 - I was left feeling empty, like "I played this game already, and it was fantastic the first time - but this is the same game, just with more melee weapons".
