So I am currently browsing steam for any kind of cool, fun, and good re-playable games. I already have portal 2, CS, and Half-Life 2 but don't know what other fun Mac games to purchase. any suggestions would be awesome thanks!
( yes i know have a mac- keep your negative comments to yourself, I've heard them all )
For me personally I enjoy Civilizations V which I would say buy from steam instead of the app store because then you get multiplayer. Also I would recommend killing floor and left 4 dead 2 both on steam.
