Somewhere in my comment history, back when Steam did their 2024 yearly awards I think, I called out someone who was trying to defend Balatro's RNG by saying that players and modders had proven that only 1 in 5 RNG seeds resulted in a truly unwinnable game on the max difficulty.
I don't know how true that is, but it definitely lines up with my anecdotal experience of the game.
That would mean that at best, playing 100% optimally (the RNG is deterministic, so the same actions on the same seed lead to the same RNG outcomes), with the ability to cheat by undoing your moves and by seeing the rng outcomes in advance... at absolute best you could only have an 80% win rate on the hardest difficulty.
I enjoyed Balatro, but that is cuckoo fucking bananas absurd.
The average player is not playing 100% optimally with full sight of RNG outcomes and an undo button... this is so beyond the realm of "just git gud scrub".
What's more important to you: having a relationship with them or changing their views? I don't mean this as some kind of "gotcha" thing. This is the choice you need to make.
You already have your simplest solution to this (don't talk politics with them), but you made this post because you don't like that solution.
Thankfully most things in life aren't so black and white. It's possible that you can work on them very very softly and slowly over time, but this all comes down to what you can stand in order to keep your relationship with them.
I personally think that attempting to avoid political topics with them is the best direction to go here, but it's not my parents or my choice to make for you.
