Slay the Spire is fun (but has aged). Luck be a Landlord is great fun too. And of course the Meteorfall series. All have a slightly different gameplay, but they’re all worth their money.
That said, I (just a casual gamer) learned about Balatro yesterday so am just a couple of hours in to it and must agree it is a blast, too!
Luck be a Landlord was my favorite out if all, Balatro might beat that but I need more hours and exploration.
