I've been playing this game recently for my XXXBox360 and found pure enjoyment in the hours I've played. It's difficult from time to time, but honestly I enjoy almost everything about the game. Although, I've not beaten it yet, but I've already gotten about 15 hours of enjoyment out of the game. Oh, and you don't HAVE to kill little girls... You just... can. Ya know? I mean, like the option is available... To kill them.
Play this one if you get the chance. I would say it's 100% worth purchase at $20, 85% at $25 and 70% at $30.
I'll edit in a game description later when I've got a bit more time.
