* ''TabletopGame/{{Exalted}}'' has The Return of the Scarlet Empress -- a campaign detailing the culmination of the [[HellOnEarth Reclamation Conspiracy]]. The final climax includes [[spoiler: the Ebon Dragon, the Yozi who ''created'' the concepts of misery, vice, cowardice and evil, returning to Creation and attempting to install himself as a fundamental aspect of Creation.]] The Exalted heroes, unlike the time when they combined their heroism and strength to defeat the Primordials, are shattered and turned against each other. The Solar Exalted, the most mighty of all, are only young and weak. Creation has been ravaged for decades by the demonic forces of Hell... But if the Exalted stand against the Yozi and fight with all their might, they might -- ''might'' -- defeat the invaders and protect Creation from another apocalypse. But it will be a bloody fight where giving up seems to be the comfortable and sensible option...
** This is Exalted ''as a whole''. The challenge isn't saving the world from horrible monsters, it's saving the world from ''yourself'' and/or making it a place worth saving.
* ''Fate of [[Franchise/CthulhuMythos Cthulhu]]'', currently being kickstarted, is about using time travel to SetRightWhatOnceWentWrong and avert, or at least sabotage, the rise of an EldritchAbomination. Getting enough positive ripples to improve the disastrous rise of a Great Old One to a survivable level will likely not be easy, and each negative ripple will make future scenarios worse, but it is possible to at least mitigate the End, and possibly even allow humanity to [[DidYouJustPunchOutCthulhu punch out Cthulhu]].
* ''TabletopGame/FengShui'' models itself on Hong Kong action movies. And as anyone who's seen a Hong Kong action movie knows, the heroes are ''not'' guaranteed to win the day or get out of things alive -- in fact, tragic endings are rather common in Hong Kong cinema. So while happy endings are indeed possible in the world of ''Feng Shui'', you're going to have to go through hell to get them.
* ''TabletopGame/NewWorldOfDarkness:''
** ''TabletopGame/PrometheanTheCreated'' is the only game in the ''TabletopGame/NewWorldOfDarkness'' to have anything approaching a predefined "happy ending"... but as this is the World of ''Darkness'', it's a long road to hope. Prometheans get some of the worst BlessedWithSuck of all supernatural types -- they come into existence in adult bodies with undeveloped minds, their very nature makes humans [[HatePlague flip out and want to kill them]] over time, the very earth rejects them, and since they're so rare (for obvious reasons), it's hard for them to band together in groups. But as they're unfinished works, they can undertake a long and arduous Pilgrimage to figure out what humanity is... and, in doing so, [[ToBecomeHuman become human themselves]].
** ''TabletopGame/VampireTheRequiem'' has Golconda, which similarly allows a vampire to escape their state -- although into ''what'' is vaguely defined. It's arguably even ''worse'', though. On top of having similarly stringent requirements to actually obtain, it's entirely within the Storyteller's power to rule [[ShootTheShaggyDog Golconda doesn't actually exist and you've just been wasting your time]] -- unlike becoming human in ''Promethean'' which is a core part of the game's premise.
** The worlds of [[TabletopGame/ChangelingTheLost Changeling]] or [[TabletopGame/MageTheAwakening Mage]] don't have quite as defined a "happy ending", but the games stress over and over that despite all the doom and gloom, there is a very real chance that a Changeling CAN reconcile their trauma and live out their lives in relative peace, and that Mages truly CAN make the world a better place if they avoid the pitfalls of hubris.
** ''TabletopGame/MummyTheCurse'' [[spoiler:turns out to be the second NWOD game to offer a possible "happy ending". The Arisen can seek Apotheosis, reclaiming their freedom, their selfhood, and their memories from the Judges.]]
** ''TabletopGame/PrincessTheHopeful:'' You are a living incarnation of goodness and Light in a setting where the Darkness has conquered the world, forced into an uphill battle against an evil that has had eons to entrench itself. But for all that, you ''do'' have real power, and you ''can'', inch by inch, life by life, bring back Light to a World Of Darkness.
* The Time of Judgment, the series of supplements that originally finished the TabletopGame/OldWorldOfDarkness lines, included multiple scenarios where the players have the chance to overcome the WorldHalfEmpty and earn their happy ending (for themselves and for the world, even).
** In Wormwood, one potential resolution for a ''TabletopGame/VampireTheMasquerade'' game, the player characters are offered a shot to atone and seek redemption as God judges the ultimate fate of all vampires. That is, if they can last 40 nights without succumbing to their beastly nature...
** Judgment, a scenario for ''TabletopGame/MageTheAscension'', covers the last moments of reality. The players will be entrusted with the means to save the world from total destruction... But in the path to achieve this goal, terrible secrets will be revealed, friends will turn again each other, institutions will collapse, nations will be thrown into anarchy, monsters will be freed to roam and feed, and millions upon millions will die. There will be too many chances to fail as magical wars ravage around them, cosmic forces hunt after them and inner weakness and flaws will surface to haunt them... But, if they fight for everything and manage to fix the error that made the world a world of darkness, ''all of humanity will be freed from the [[EpiphanicPrison shackles of doubt and disbelief]] and [[AscendToAHigherPlaneOfExistence Ascend]]''. Hard to ask for a happier ending for the entire universe.
** There are a number of scenarios for ''TabletopGame/WerewolfTheApocalypse'' where the much-feared Apocalypse comes to pass... and just as many that say, "If you knuckle down, atone for past sins, and strike true, you will win against the Wyrm." The 20th Anniversary edition reinforces this, with a comic where the Prophecy of the Phoenix (the account describing the Apocalypse) is reiterated... only for a new clause to appear, effectively saying, "But if you stand and fight instead of wallowing in hopelessness, who knows what'll happen."
* ''TabletopGame/WraithTheOblivion'' was, in many ways, the precursor to ''Promethean'', only even darker. Right, so you're stuck in a decaying afterlife with the foot soldiers of Oblivion, a power-mad undead empire that would just as soon ask for your vote as melt your corpus down to fill the treasury, and [[TheHeartless a voice inside your head]] trying to convince you to give it all up and tear the world down. But if you can remember what made you human and come to terms with the [[UnfinishedBusiness ties that bind you]] to this world, [[EpiphanicPrison you're free to move on to the true afterlife]].
* ''TableTopGame/GrimHollow'', a ''TableTopGame/DungeonsAndDragons'' setting focused on DarkFantasy and GothicHorror, takes place in a CrapsackWorld where the [[GodIsDead gods are literally dead]], monsters lurk in the shadows where they aren't ruling openly, a lethal plague is sweeping the land, superstition and suspicion are rampant in people's hearts, and the various nations are busy fighting each other rather than trying to fix anything. In spite of all that, the Player's Guide goes out of its way to discourage TooBleakStoppedCaring, encouraging players and DM's alike to focus more on this trope: yes, the world is awful, and at times it feels like the universe itself is resisting your attempts to make it better (and it might just be), but all that means is that every victory, every happy ending, and every life saved was something ''earned''.
* ''Heart: The City Beneath'' has one Zenith ability that is this. It's a horror game about delving into a broken dimension where reality is [[RealityIsOutToLunch permanently on break]], and most Zenith abilities involve dying in a glorious TakingYouWithMe kind of way, or at least going irrevocably OneWingedAngel. But if you're an Incarnadine, a priest bound to the god of debt by your massive, well, debt, one of your options for a Zenith ability is Ultimate Reward: you finally pay off your debt and retire from the dangerous life of a delver, to die some years later surrounded by your loved ones. Advancing far enough to buy this ability is incredibly deadly and will screw you up bad if it doesn't outright kill you, but you can do it.
