Undertale / Deltarune

by Toby Fox

Undertale is an RPG where every enemy can be defeated without violence — or destroyed completely. Your choices permanently affect the world, the characters remember your actions across saves, and the game's meta-awareness of being a game creates one of the most unique narrative experiences in gaming. Deltarune continues the themes in a connected but distinct world.
