Then there is the classic Nintendo approach: "so you've put a lot of effort into this game? Well, you better keep coming back every day or we'll chip away at that".

- Animal Crossing: your island may become overgrown with weeds, villagers want to move out, some furniture will rust, your home will have cockroaches

- Nintendogs: the puppies will get very hungry and thirsty, they'll lose weight and stop recognizing your voice.
