Persistence in Perma Death Generating Games

The optimal length for one of these like, Perma death generated games where you don't have anything going on that like persistent upgrade stuff is like 45 minutes to an hour. We can't ask people to just do it again and again every day. Unless you're making rogue, right, which you're not. So I think there's a lot more mileage in that really cool comic book style that we could probably get something out of it. But again, the daily depends what kind of game it would be. And maybe it's a miniature version of the star map and you just have to figure out how to min-max your way through it.
