If I buy a game somewhere other than Steam (say, Amazon who has a great download sale right now), and then register the game on Steam for the convenience of having it in the Steam library, does this reduce any playing options than if I just installed it outside of Steam? Does it require Steam to play if I register it there?
I've done this with a couple games, tonight was Mafia II ($12.50!), and before I do it with more, would like to know if has restriction, the Steam message seems to suggest it.
