Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Buyer beware

I just bought this game, used from an Amazon seller. My advise is if you're considering doing the same thing, DON'T. It's a Steam game. And as such the cd key has already been activated on Steam. It is not transferable. In my case the "key" I got was hand scribbled on one of the cd sleeves and was a non functional number. So now what I have are five, tiny frisbees, or if you prefer, coasters. Their too light to be paper weights. Needless to say the seller is going to get a negative review. I just thought that this in info. you can use.
