I've funded more than a few RPGs through Kickstarter in the prior years. However, I have played few of them, thus far.
One that I just received was Downfall, which was originally released here as a Kickstarter. It is described thusly:
Downfall is a tabletop role-playing game that explores the collapse of a society, a cataclysm brought about by a fatal Flaw at work within it. First you sit down and build your world, then you destroy it. You tell the story of a hero who tries to save their home. But in Downfall, the hero fails.
I got my copy in the mail just over a week ago, and got a chance to peruse the 70 page manual, and I really like what I've found.
I'm a big fan of a few of the narrative story (aka "hippy") games I've played, such as Microscope, The Quiet Year, various postworldgames, and The Fall of Magic. Most of these games don't even have a randomizer. They're basically story exercises that are fun to play with people who aren't assholes.
Downfall is very similar. It's quite specifically a 3-player game, where the players equally help create the society, as well as the 3 main characters (a protagonist "Hero", an antagonist "Fallen", and a third character, the "Pillar". One aspect central to the game, and the very first thing you define, is The Flaw, around which the whole scenario rotates. Six Traditions will also be defined, which come up in various parts of the game.
The players will take turns playing these characters throughout the game, as the society slowly collapses. Play time is variable, but I suspect a 2-4 hour window would work.
Haven't played just yet, but it's on my short list. I hope to write again about it once I've played. Fortunately for me I've got a work gathering with some gamer friends in a few weeks, and it's magic number: THREE of us. This'll be on top of the pile.
Downfall can currently be purchased from <3 Games.
