This game is just phenomenal, I find myself thinking about the game and it's creatures late at night while trying to sleep. It has a quality to it that requires your undivided attention and I think that's why it permeates so easily into your psyche.

If you haven't tried it out yet, do yourself a favor and at least rent it. It's one of the best game to come out in the past decade. You'll hear people whine about it being hard, but it's not like that. It's fair. You mess up you will be hit. If you're patient and time your movements you'll glide through the areas and make the game seem like a typical hack n slash. You will make it look easy.
