Yeah, I'm expecting 85ish, for a few reasons:
a) Higher levels of expectation after Xenoblade Chronicles' highly positive reception.
b) A handful of reviewers will make negative comparisons to other open-world games launched this year. I'm particularly expecting complaints of "It's not all narrative driven the way Witcher 3 is"
c) The story/soundtrack will be seen as inferior to XC.
d) There will be complaints about how overwhelming the game initially is, and about the lack of handholding.
e) At least one reviewer will hate the battle system.
That being said, I'd love to be wrong and see this get a better reception than Xenoblade Chronicles! My pre-order is sticking regardless.
