I have the disk version on ps4 and waited until after Xmas to play due to all of the negativity surrounding the game on GAF, despite loving JC2.
That was a mistake because its the most fun I have had in a game on my PS4. Just the traversal in this game is more fun than most games. It does slow down a bit sometimes but the positives far, far outweigh the negatives IMO.
Still haven't quite completed it yet but I have a good 30 hours played and cant wait to get stuck into the DLC.
