Does this game have any replay value in the single player campaign?
I replayed it twice immediately and I'm going to replay it again. For me, I went from normal without listen mode to survivor. The game changed pretty dramatically.
The thing that gives it replay value is the depth of the combat system. After your first playthrough you've gotten really good at the mechanics and using all the tricks you've learned in the campaing from the get go second time around makes the earlier encounters much more satisfying.
I'd say that a difficulty hike is probably necessary for the second time to be satisfying though. Fortunately, they've got normal, hard, survivor, grounded, so that's probably not going to be an issue.
That said, it's a pretty long game anyway. Between 15-20 first time around, not counting the DLC. Which is easily 2 hours.
