These kids are stupid, because Undertale was created thanks to Touhou, Minecraft is inspired by a game (I forgot the name) which had the same concept to be so popular, I can quote many more examples . It could have been said that Zun is a plagiarist and that Toby Fox plagiarized a plagiarist. What many people do not know is that it's called inspiration, and because of this way of thinking, the man could evolve.
