A game that is one of the best ever made. It is created by Toby Fox and Temmie Chang. It has a great storyline, music, characters, but not the best fandom. It is almost always at war with the FNaF fandom or is being jammed with bad fanart. It's a great game though! There are many AUs like Underswap, Underfell, ErrorTale, Flowertale, Gaster...Um...He is just Gaster Sans I think but, ya! Amazing game, okay great AUs, sometimes nice Fanart, but a not-so-good fandom.

A game where people are a character where they can pick a name. The characters true name is FRISK. Also, teenage girls who haven't ever played the game are obsessed with an obese skeleton and make him have a glow in the dark pp
Person 1: Hey do you know undertale?
Person 2: Oh that weird ass game where teenage girls cream over a random fat skeleton?

A small indie game with on of the worst communities that will harass youtubers for playing the game their own way and harass other people because of fandom ships.
