Huh opposite for me. I have played Slay the Spire for like 2000 hours. I have beaten it through ascension 20 on all 4 characters like 20ish times at this point. I still pick it up and play it when I'm bored and it still is fun somehow.

I could not get into Balatro like that. I think I have roughly 50 hours in it and like 3/4 of the way through it with all the decks and challenges and simply cannot bring myself to complete it. The last 10 or so hours just felt like a slog. Still a good game but the sheen wore off for me well before I could 100% it much less start replaying.

To each their own I guess! Funny how similar the games are and how there's just some people that love one but can't get into the other.
