I almost also wrote that I wanted something like dark souls, but built for co-op from the ground up. The dark souls games typically have a fair amount of stuff each player has to do alone, and you’d have to do the game twice.
It’s still fun and I actually coop’d the franchise with a friend, but I don’t think I could get my “plays bejeweled” or even “plays Mario games” friends to do it happily.
(There is Remnant, but it didn’t really do it for me)
