How exactly could a game, that’s supposed to be single-player, have a toxic community? Good question. It all comes down to reputation.
We agree with most people that Undertale is a fantastic game with clever humor in writing. However, there are some folks who take the word good and twister into factually perfect.
There are a number of Undertale fans that live and die by this game and if you so much as say anything about it, you know nothing about videogames and *insert threats and profanities here*.
Fortunately, there are more lighthearted fans who love the memes that have spawned but even that has grown tiresome to bear.
