An RPG game made by Toby Fox with a terrifying fandom. The game itself is good but fan fiction and alternate universes ruined it.
Undertale is great, but have you heard of Undertail? Or maybe even Sans fangirls?

An new indie game that was just like any other game, has a story, has characters, and was not intended to really be anything more than just a game. Until the community around said game turned into pure cancer, and i do not use this word lightly. And if you are one of the few people who actually dislike the game and its community you might as well be a Jewish citizen in Nazi Germany, if they find out, they will give you hell. And they will not stop
I have not gone more than a day without hearing mention of undertale.

An indie RPG created by Toby Fox that has sold extremely well and seems to have taken over the Internet.
The game follows the story of a human child who has fallen into The Underground, a society filled with monsters after humans sealed them away in a war long ago.

In battles, enemies attack your soul (which looks like a heart) in a bullet hell-like method, and you can either fight them, or via the ACT and MERCY buttons, figure out how to spare them.
The game's story is affected by how many monsters you kill, as well as which 'Boss Monsters' you kill.
It can be hard not to stumble across spoilers of this game when you are looking into it, as many popular characters are considered 'Walking Spoilers'.

An RPG game made by Toby Fox, has the bullet-hell style but also has one of the worst communities people ever known, making so much hate to it. The storyline is fine though. The acronym is UT(UnderTale).
UT player: Yo, you played Undertale?
Someone: No.
Ut player: You should try it out!

Undertale is a RPG with amazing characters, story, etc. It was created by Toby Fox and was released in September 2015. Although the game is great, it’s fandom has gone to a dark place filled with skeledicks, big tittied goat ladies, and lesbian sex between a dinosaur and a fish lady. extremely great content.
“Hey have ou seen Undertale?” “Yeah. I hate its fandom, but the game is good tho.”
