Incredible graphics, fun gameplay, and an immersive story. It's a shame it wasn't longer. Also bears great multiplayer.
Crysis 3 acts as a fantastic finale to the series. That being said, If you have not played BOTH Crysis 1 and Crysis 2 before playing Crysis 3, your experience will be substantially dampened. Crysis 3 bears the most depth in story compared to it's predecessors, being the first Crysis game that actually made me feel a considerable amount of emotion. Crysis 3 serves as a decent sequel to Crysis 2, as well as the successor that Crysis 1 originally deserved. Crysis 3 also features many open areas to explore, making it evident that Crytek has made an effort to pay respects to the open world elements in Crysis 1. Heavily acknowledging the events in both Crysis 1 and Crysis 2, Crysis 3 wraps up the trilogy beautifully.
While it is the shortest, it may be the strongest. I hate to use such an overused term, but this game is simply epic.
