I'm a diehard Amazon fan, why did I just get downvoted for providing useful purchasing information? ARGH!? you people.
Why did Michael just get upvoted for saying "No it's not only the singleplayer. Not the full game." There is a typo in there because the 2 statements don't even make sense together. "No it's not only the singleplayer" means it includes multiplayer, but then he says it's "not the full game."
You are too critical on your grammar. People are either in too much of a hurry or just don't care if their posts are grammatically correct. Kudos to you for catching it though. I think he meant "one player only" version.
