I'd love a newgame+ mode. I want to play the single player again on brutal difficulty but I've already collected everything in the game. I would probably play again on brutal difficulty if some of those unlocks could carry over. Not story unlocks but if: the bound serpents remained unlocked with the health bonus. buried metal so there's a wide range of songs in the beginning, some solos, and some of the purchased upgrades could carry over that would be great for a second playthrough. They could even add new collectibles only for brutal difficulty so there's still reason to explore again.
