10. 10 Candles
10 Candles is described as a zero prep, tragic horror storytelling game. This system is made primarily for a one-shot and a game usually lasts around 2-3 hours. There is one big way in which 10 Candles stands out from other games in this list. Your character will die. Once you accept this, the game makes for some great atmospheric storytelling.
The story follows a society where the sun has gone out 10 days ago. 5 days ago, they came. This society could be anything you choose, modern-day, ancient Rome, or even an alien world, it doesn’t matter. The same goes for the monsters that are only explained as Them. Killer clowns, demons, or an alien race, there just reflections of your fears.
The game consists of a unique timer system. Throughout the course of the game 10 tea candles are lit. When the final one of these is extinguished, then the game ends. This also allows you to ceremonially burn your character sheet when the inevitable happens. This game is all about storytelling. You will not defeat the bad guys, you will not save the planet, you just have to come to terms with your fate and make the most of your final hours.
