Why not keep the game open and everyone play as they like?
I don’t know how successfully I can argue this in a blog thread, but: it’s up to the developer to create a consistent, enjoyable play experience. If the devs attempt to create a game where “everyone plays as they like”, you’re likely to end up with a muddled, unfocused, or at the very least, unbalanced mess.
Creating a game where the player decides who he’s going to start with, how powerful they are, what backgrounds, perks etc. is fundamentally different from what they’ve got now, and 99% of players are going to start with three professional fighters every single time. Overhype has so far developed a challenging, brutal game where the player experiences real consequences. Diluting aspects of that potentially changes BB from a tense, suspenseful experience that people will talk about for years (Dark Souls) to a good tactical combat game that people thought was fun (so what?)
Look at what the devs of Darkest Dungeon are doing. Do you think people would be raving about that game if they could save whenever they want? If they could get a do-over whenever their party was wiped out?
