* ''Roleplay/DinoAttackRPG'', especially near the end, contained exceptional (and at times extremely gruesome) violence, sexual undertones (along with one or two implied scenes), a sub-plot about a lesbian and her homophobic father, a character whose mother is implied (and confirmed by WordOfGod) [[SonOfAWhore to be a prostitute]], extreme sexism, implied genocide, drugs (including an overdose), child abuse ([[KarmaHoudini and the man responsible gets away with it]]) characters who explicitly smoked and/or consumned alcohol, post-traumatic stress disorder, philosophical discussions, two characters with sub-plots concerning their religious faith, BodyHorror, an unstoppable EldritchAbomination [[CosmicHorrorStory on an almost Lovecraftian scale capable of destroying the planet and possibly the entire universe if it were to ever get out]]... and did I mention that this was all based entirely on a [[LEGODinoAttack short-lived LEGO theme]]?
* ''VisualNovel/DanganRonpa'' is already dark, but ''Roleplay/DoubtAcademy'' takes it even further thanks to a few key differences. Unlike in canon, where convicting the wrong person equals GameOver, here [[HangingJudge Monobear]] simply tells them they got it wrong before executing the innocent scapegoat. This creates a KangarooCourt atmosphere where classmates have already lynched someone they ''knew'' was innocent to keep them from taking revenge and others have offered themselves up as {{Senseless Sacrifice}}s to keep their friends from suffering the same fate.
