You're recommending Slay the Spire for the lore? It doesn't even have lore.

1: Have you played through it?

2: The GP talked about “worlds”

1. Yes, of course.

2. What are you saying?

Do you need everything to be verbosely narrated out for you to consider it “lore”?

There’s some good worldbuilding and backstory in StS, but you have to play a lot to comb through all the random events etc. to discover it. It won’t sit you on its lap and read to you.
