Nice RPG's

Me and me mates need some neat RPG's to play, in multiplayer. Something action-packed, Diablo style would be prefered. Of course we're looking for a co-operative type.

I've browsed around on some review-sites like gamespot but haven't really found anything useful yet.

Games we've tried already or don't want:

[*] Diablo/Diablo 2
[*] Dungeon Siege/Dungeon Siege 2
[*] Mage Knight Apocalypse

Well, that's about it I guess. Help is appriciated :O)
