I honestly only play a gacha game if I like the gameplay on some level. There has been a few Ive enjoyed

Punishing gray raven

Date a live pledge spirits

Mega man x dive(offline version)

Honkai impact 3

Action taimanin

Taimanin squad

All games that I play for the gameplay as they remind me off 6th gen console quality somewhat.

I put a little money into them but nothing much.
