Thanks a lot for the recommendation, wishlisted; Chocobo's Mystery Dungeon (the original, Japanese-only one) was my jam during the late 90s, long before I knew what a roguelike was. On zooming the screenshots, I see they're highly detailed art rather than 3D models as I had assumed, which is a massive plus. I'm not getting it right away only because I'm swimming in Switch titles right now and short on cash (the woes of indie development).
I might finally break down and buy it tonight. Have to gauge how much time I think I can devote to it given my recent re-obsession with Stone Soup. I've watched some footage of it and was impressed by how tricky the game can get with that rune system in place. There's definitely more going on there than a simple rogue-like-like imitation. Are all the Mystery Dungeon games fairly difficult?
