I bought it for COD 4 , when i was young I love it, it is still a great fucking game, and people cry about spending 80$ for entertainment that they will spend hours on? Sounds like a good deal to me.
My review - 16 Maps will be out by December, and as the first COD game i played on PC i would rate 9/10 only reason it's a 9 and not a 10 is because the servers are slightly fucked and if people leave your game it takes a long time to get the teams balanced out ( even numbers )
