So when my uncle saw that everyone on the server is a frog, he had the suggestion that every few days, everyone is a prince-type character
Haha. Something similar did cross my mind... But kind of the opposite. There were some players that were princesses and now their nightmares have come true. They are a frog.
I think that that is an improvement actually.
It will keep discussion on the game instead of turning it towards unsavory subjects
