Well, I just finished FEAR, and, IMO, it has one of the best stories ever. An excellent twist at the end and the developers did an excellent job of keeping you in the dark until the end. The mark of a truly great twist is when you've been told that there's a huge twist and you'll NEVER guess it, so you spend the entire time trying to figure out the twist, only to get smashed upside the head with a REAL twist. The only other time that happened was with Saw, a great movie. Its a short game but absolutely amazing. 10/10.
