One great massive pat on the back for Ubi Soft, this game could be the best I've ever played and I've been into games since 1986!
This really could be the best game ever, not felt like that for a while. The fact it's not a modernistic FPS with crazy weapons and gadgets adds to this game in some way. I felt really immersed in this world and had some attachment to the nature.
This ranks up higher in my opinion than the mighty Half Life!
