I would love Lan and co-op and would gladly pay extra if it came in the future.
I know alot of you didnt like the co-op in BG2 but that single feature is the reason I still play BG2 after so many years!
I must say I really enjoyed the co-op in BG2.
It made me play the game so many times with diffrent friends.
I would love to see co-op in enernity aswell, and yes I know it prolly wont heppen since it would take to much effort and time, but one can hope atleast =()
