This is going to sound weird. Castle Morihisa is a good game and I had fun playing it. Weird, right? That said, I would recommend Castle Morihisa to no one. Why? Because what Castle Morihisa does is it takes Slay the Spire, changes very little, and delivers a lesser experience. Sure, it's still a good game and imitating one of the best deck-building roguelikes out there--hell, one of the best games period--but it stays too close to the original and what changes it makes are for the worse. Because of that, there's no reason to play Castle Morishisa over Slay the Spire or other games that do a better job of being their own thing (unless you've played every other deck-building roguelike and you just want more of the same with a fresh coat of paint, because that's all Castle Morihisa is).
