In-game timers that make you arbitrarily wait for something.
"Weekly events - you play 7 games and then they make you wait a day or you have to watch an ad"
"Every action takes a certain amount of time to complete, often somewhere around 30 minutes just to cook something in game for one. Most of the game consists of waiting and there's a max to how much you can do in a day"
"Amount of actions you can take is limited by an energy bar you can pay to get past"
"There are certain activities you get limited time for and have to wait to then play again, and there's also a limit of experience you can gain before it starts telling you that you're "losing" experience by not waiting for it to fill back up again. However, you can just keep playing without getting extra experience if you want to ignore that."
