@mosdl: I dont know about the others, but Lego Lord of the Rings has amazing couch co-op. Keyboard controls kind of suck, so 2 wired controllers is the best bet. But it does divide up the keyboard too so that both players can play on one keyboard. It was awesome the first time I played with a friend because we were in the world map and I just said "Lets go pick up a quest in Bree" and fast traveled to Bree. I was jaw dropped for a good couple of minutes when only I traveled there and he stayed in the world map. Both players can play it in completely different sides of the world.
