Gaming

To be fair, a pity system should definitely be a thing if there's any sort of gamba. That way there's at least a hard limit on what you can waste your money on until it's guaranteed. I at least find GI characters not to be too predatory, you mostly pull them for fun. In fact some of the best characters are the starting 4 stars lol, and you pull cuz you like the character a lot. They really develop the characters a lot, and if you've seen any comic cons or anime conventions, you'll see an insane amount of Genshin cosplays cuz they suck you in by really loving the characters. The gameplay is honestly so easy you absolutely don't need a good character, and it's actually incredibly balanced. The earliest characters released are actually still S tier because they fucked up the balance a bit with them so the new characters are still good but more niche focused, so everything is still relevant.

The only hard content is what's called the spiral abyss, which is a completely optional dungeon that rotates every 2 weeks and 100% clearing it gives you like 5 free gacha rolls, so people really just use it to bench mark characters since nothing else in the game is remotely challenging, nor is there any pvp aspect or anything.

But yeah, also Gacha and live service games tend to be a drug, once they have you hooked it's hard to quit. Sunk cost fallacy is real hard to overcome in gacha games.
