Chants of Sennaar is my absolute favourite and I also really enjoyed The Case of The Golden Idol.

I haven't found anything close to scratching that Chants of Sennaar itch so far but I will check out the other games you mentioned as I haven't played any of them.

I also loved the conceit of the Obra Dinn but the visual style made me feel physically ill to the point I couldn't continue with the game. I'm useless with any first person POV stuff in general though.
