Good coop games?

Hey. Im looking for some good coop games. iv already played most well known coop games such as,Rainbow Six, L4D and L4D2, SWAT 4, killing floor, ghost recon, Arma , borderlands. I already bought and completed all the portal 2 coop levels. Just looking for some coop games. or mods. Im already aware of all the Half life and Half life 2 coop mods. Any recommendations?

Total War Shogun2 is one of the best coop games ive ever played and strategy games usually are not one of my fav.

Magika, good fun in coop for a cheap price.

Titans Quest or Neverwinter Nights2

Diablo2 and its expansion pack

how about Portal 2!

Some of the ones I've enjoyed:

Trine
Lara Croft: GoL
Resident Evil 5
Borderlands

Titan Quest is really fun with another person.
