Summary: great game but... i over looked one detail you need to download 3rd party software to run it and create a new account through it to even begin. if you don't want yet another useless account and more junkware bogging down your computer just buy the hard copy while available. my fault over all for missing the "steam client" warning.
Summary: First played this on my college roommate's Xbox and loved it. Bought the pc game as soon as I found it, but lost the play CD at some point. Excited beyond belief when I saw Amazon had the download. This is my favorite game and I could play it over and over, finishing the game within a week or two depending on how much free time I have.
