Yume Nikki (meaning Dream Diary) is a freeware RPG Maker game created by the illusive Kikiyama. The first version of the game was released back in 2004, and the final was released in 2012. In 2018, the game was added to Steam, and in that same year, a derivative game known as "Yume Nikki: Dream Diary" was released.

The game is a cult classic in the JRPG community for its untraditional style of gameplay! Because, for an RPG... there's practically no story elements whatsover. Not any real dialogue, nor any sensible interactions between characters... Yume Nikki really does feel like you're walking through a dream, where everything is hazy, absurd, and asinine. Nothing but symbols everywhere you go... It makes you wonder what it all means, if anything at all. And that's why this game is so neat!
