Also there isn’t anything that hasn’t been done before either in Balatro, it’s just a nice combination of deck builder tricks applied to poker. And the presentation is also well done which has nothing to do with the mechanics.
Balatro took the basic game mechanics of a very familiar game and said “what if they were dynamic”. The world’s a big place and I’m willing to believe it’s been done before… but I can’t think of one.
It’s the combination of familiar scoring mechanics with fun meta game modifiers that made Balatro so successful. What happens to poker if two of a kind is suddenly the most important hand? Or if not playing face cards leads to incrementally better scores every hand?
Again, I can’t claim it’s never been done, but saying it’s just another deck builder is missing the point.
