The story of how Toby Fox created Undertale begins long before the flower on the save screen or the battle animations that stole millions of hearts. It is a narrative woven from the threads of classic gaming nostalgia, personal struggle, academic curiosity, and a profound desire to redefine player expectations. Understanding what inspired Toby Fox to make Undertale requires looking at the influences that shaped his design philosophy and the specific circumstances that allowed this small-scale project to become a cultural phenomenon.
The Foundation: Influences and Early Development
Before examining the specific catalysts for Undertale, it is essential to acknowledge the broad foundation of inspiration Toby Fox built upon. His work was not created in a vacuum but is a direct dialogue with the games he loved as a child. The influence of classic RPGs is undeniable, particularly the progression systems and world-building found in titles like EarthBound and the SaGa series. These games taught Fox that narrative could be non-linear and that player curiosity could be the primary engine for discovery, a principle that would become central to Undertale’s design.
Dungeons & Dragons and the Power of Imagination
A significant portion of Undertale’s DNA comes from tabletop role-playing games, specifically Dungeons & Dragons. Fox’s background as a session musician for actual play shows like "Homestuck" (which he also contributed music to) immersed him in the collaborative storytelling inherent in D&D. This influence is visible in Undertale’s encounter system, which relies heavily on player intent and observation. The "ACT" menu, a direct lift from D&D terminology, empowers the player to read an enemy’s emotions and intentions, turning combat from a simple stat check into a nuanced interaction that questions the morality of violence.
The Shift from Music to Monster Battles
Interestingly, Toby Fox did not originally set out to create a full-fledged RPG. His initial foray into game development was a technical demonstration rather than a narrative project. He created a battle system inspired by the bullet-hell mechanics of Japanese shoot 'em ups, combining it with the musical style of rock and metal songs he was composing. This prototype, which lacked a story or setting, proved that the core gameplay loop was engaging. The challenge then became finding a world worthy of these satisfying combat mechanics, leading to the creation of the Underground and its inhabitants.
The Human Element: Frisk and the Player Avatar
One of the most brilliant inspirations behind Undertale’s design is the concept of the "avatar." Unlike the silent protagonists of old-school RPGs, Frisk is a distinct, silent child character who stumbles into the Underground. This choice was crucial because it created a clear vessel for the player. By making Frisk a mute observer who reacts to horror with silent tears rather than dialogue, Fox allowed the player to project themselves into the role seamlessly. This subtle choice fosters empathy and forces the player to confront the consequences of their actions directly, without the barrier of predefined personality.
Challenging Conventions and Player Psychology
What truly set Toby Fox apart was his willingness to deconstruct the expectations of the genre. He was inspired by a desire to subvert the power fantasies common in RPGs. Instead of grinding to become more powerful, Undertale asks the player to consider if they should become more powerful at all. The game’s genius lies in its understanding of the player’s psychology—the excitement of winning, the frustration of losing, and the moral dissonance of attacking a harmless, fleeing enemy. This inspiration from human behavior allowed the game to bypass traditional gameplay loops and deliver a message about mercy and consequence.
