game idea for making fobucks ?

i kind of want to make a game that’s embedded in the site that you can make fobucks playing, that way you don’t have to be super duper active as the only way to make fobucks. i’m curious what type of games you guys would prefer:

• idle game that does stuff for you when you’re offline and you make upgrades when you come back and repeat

• gacha / gambling game

• fishing world where u can make fobucks off selling fish and u can talk to other ppl online (multiplayer)

these are just the ideas off the top of my head but im curious what you guys would enjoy the most so feel free to give suggestions, ideas, etc.
