Guilty Child confused everyone since it was actually a bastard game.
Scum InnoChild isn’t necessarily unfair, but simply annoying.
If you want to know what unfair is like, then try playing Rokugan FM: Without doing anything, the game already ended because half of all players in that game threw away their lives by claiming their role and thereby not only committed suicide, but also killed the other half of the players who actually wanted to play the game. Now THAT is unfair.
