Unlike the games in Liar Game, the rules of a Danganronpa game are sometimes made up or stated midway, which for me kind of sucks but is tolerable so long as the rules are consistent.
In Liar Game, afaik, the dealers always account for all possible situations and state consequences of the situations outright especially when there are changes. For example, in games involving voting, the dealers state what happens in the event of a draw, even if it later doesn't occur or even factor into some calculations made by the characters. In one voting game, a draw was not possible because of an odd number of players (well actually, assuming everyone votes). Later, the number of players became even, so the dealer of the game immediately stated what would happen in the event of a drawn vote.
Iirc, a PA is made, after 3 students discover a corpse, announcing that there will be a classroom trial called.
What if there is no corpse to be found, like the body was burned (alive or dead)?
What if student A is murdered, and the corpse is hidden for a long period? Can the game continue with an unannounced or unresolved murder?
PS I'm done with the anime. Go ahead and spoil other media. But please use spoiler tags for others.
