Reviewers Didn't Like
- Combat becomes a chore in the latter game
 - The pacing in the middle of the game drags down the experience severely
 - Cumbersome menu system
 - Unique, asynchronous multiplayer option opens the door to annoying trolling
 - The story is a little self-indulgent
 - Might not run on lower-tier PCs- Not super different from console version
