While not mentioned anywhere on the requirements either on here or on the game system requirements site linked to in the description, this game REQUIRES a Steam account in order to install or play it. This crucial piece of information is only able to be found out after you have purchased the retail version and should be listed more clearly in the product description. Games should NOT require yet another username and password just to play them when they are not even online games! –2 stars for yet another game developer deciding that players must be online in order to use their product.

very easy to set up game and the graphics are amazing better than i thought and the controls are also great i use a xbox 360 controller which makes it more fun plenty of missions to do which are a good time waster if your bored but when you install make sure your connected to the internet download register free account/login to steam if you havn't done so allready then when you put the disc in just follow the simple on screen intructions happy train driving best of all it does install from cd you just need internet for product activation and installation if you havn't downloaded steam for installation yet heres the link if you don't know anything about it http://store.steampowered.com/about/
