>barely 6% of the players have completed even a single run with each of the 8 characters
this is literally the least-completed achievement in the game, excluding the "get all achievements" achievement. 8 isn't even a lot of characters, and people still aren't giving them all a try. are people really so boring that they just want to play the same character every single run? that sounds like most unenjoyable approach possible to playing a repeated runs-based game like Nightreign.
