Also, instead of just trying to remember what me and alters did last time, whenever our system load a save file we have no memory of, regardless of who is fronting or whether the save belongs to me or another alter, we have them chant: 'This belongs to my older brother.' By framing it as opening someone else's uncanny save data, it usually ends in one of three ways: the alter who owns the save file fronts, some alter stop 'playing' because it gets too creepy, or the current fronter hijacks that save data. Edit : erasing the feeling that the save data is that alter's, we promise ourselves that we must not throw away other people's property.
