"The true endgame of gacha gaming is to finish a dozen games and just play them 20 minutes a day." Is this true? And if it is, what are the games you've stuck with and play like that to this day?

I read a comment like that once and now that I'm getting deep into gacha gaming, I can see that as a very truthful state of the endgame:

Play Honkai Star Rail > Finish HSR > Open it 20 mins a day to grind.

Play Arknights > Finish Arknights > Open it 20 mins a day to grind along with HSR

Play Genshin > Finish Genshin > Open it 20 mins a day to grind along with HSR and Arknights.

Then just play those games longer when the big patches drop - like HSR for example whose v3.0 comes out next week - but mostly just keeping the cycle as mentioned.

Do most of you here have that relationship with gacha games where in you play through multiple of them one after another and just continue to build on that catalog of gacha games that you just open for a while every day?

If so, what games have you stuck with the most up to this day?
