So I was wondering that what games do You recommend for LAN / CO-OP play?
Depends. What games do you and your buddies prefer? RTS? FPS? Trivia? Board games even? XD
Being me, I like to play (side by side/across the desk from one another) Counter-Strike or Call of Duty type games.
If you like RTS's and haven't played many of the older ones, go for games such as Age of Mythology, or if you're experimental or REALLY like the older RTS's, go for Total Annihilation: Kingdoms. Or the original for that matter.
Those are just what we've played recently.
Not an RTS guy... i enjoy games like RE5 and Rainbow Six, that kind of stuff. I don't really do any cooperative stuff on PC, it's mostly PS3 when I have a buddy over or something. I prefer playing shooters alone but the co-op mode is solid enough it can be a lot more fun playing with a friend.
