Fraser Simons​​ there are three grades of sheet that escalate the complexity of the game while being internally compatible. So my wife plays circle and my daughter played triangle and they intersected with the game in the same way.

The practical effect of leveling up your character sheet is gaining more cool stuff. It’s pretty motivating! My daughter was feeling salty that mom’s robot dog companion could do stuff and her pretty pony companion could not.

It’s the killer app of the game imo.
