* ''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.
* The ''Insane Cafe'' [=RP=] trilogy has elements of this. The first was a nonsensical, hilarious and downright {{Narm}}y. The second was more plot driven and a terrorist attack on a remote laboratory was a key plot point. The 3rd installment features several assassination attempts, [[HotterAndSexier a few sex scenes]] and an impending war. Oh yeah, profanities are uttered the second and third installments.
* While most of the campaigns in the ''Roleplay/GlobalGuardiansPBEMUniverse'' were standard [[UsefulNotes/TheBronzeAgeOfComicBooks Bronze Age]] fare, the ''Night Life In The Big Easy'' campaign, which featured a solo 1980s-style vigilante facing off against a voodoo-themed criminal empire that had been built on drugs, prostitution, and white slavery, was straight out of the DarkAge.
* ''Roleplay/WelcomeToBeacon'' and its sequel ''Roleplay/WelcomeToBeaconUltimate'' are considerably darker than canon ''WebAnimation/{{RWBY}}''. The Grimm are a more considerable threat, and the students have to face two major criminal organizations, who have no qualms causing deaths and grevious harm to the student body. Several characters also carry scars, both physical and mental, from prior encounters with the Grimm, and sex between them have been implied several times. There's a reason several players call it "RWBY as written by Creator/GenUrobuchi"
* ''Roleplay/PokemonRiseOfTheRockets'' started out as a straight-up WarFic of {{Franchise/Pokemon}}, with its very first seen being the execution of Rocket Leader Giovanni, and has only gotten darker from there. Doesn't help that much of the MindScrew, [[DespairEventHorizon Despair Event Horizons]], [[MoralEventHorizon Moral Event Horizons]], and overall violence has been [[WordOfGod inspired]] by such series as ''Anime/NeonGenesisEvangelion''.
