Issue: Are they able to copy games between devices?
if yes: Then they're going to end up playing games they get from other households that they don't directly know the authors of.
if no: Then they can't really collaborate on the games very well which is sad.
Maybe just let them copy but make sure they understand the point of it: you get to participate in a creative ecosystem, you get to make your own games.
