Yeah, I went down a similar path as well. Fairly similar type of game too. Content just felt bottomless. I thought AI could fill the fluff but really it's one of those things where you spend a 1-2 man days writing 10 minutes of gameplay worth. I would say that building the content generation engine is a really big part of the genre. I actually built a tool for it, which was a big part of holding my sanity throughout the bootcamp.
The game reminded me a bit of Cultist Simulator/Book of Hours, which I loved. It's a bit of a puzzle, the hints are unclear, but spotting patterns in how the cards match, you'd figure out which cards to play.
But do let me know if you want to work on something together next time. Seems like we have similar tastes and approaches.
