I very rarely give single player games a chance, but I've made an exception for Alien Isolation and so far I'm not disappointed. It's not anything new or innovative, but every little aspect of it is just extremely well done. I'm not sure I'll have the patience to get to the end of it, but so far I'm really enjoying it. Although if you're thinking of getting it, it will most likely be slightly discounted during the Steam Halloween sale, so wait for that.
