To be fair, you have to have a very high understanding of games and art to appretiate Undertale. The humor is easy to catch, but without a solid grasp of the exensive history of videogames, and heavy knowledge of ALL RPGs, the true jokes will go over a typical player's head. There's also San's nihlistic outlook and existentialist outlook, which is deftly woven into his characterisation - his personal philosophy draws heavily from the likes of Friedrich Nietzsche and Albert Camus, for instance (both who's ideals have transformed extensive amounts of characters in current time's gaming culture). The true fans understand this stuff; they have the intellectual and mental capacity to truly appreciate the depths of these jokes, to realize they're not just funny - they say something deep about LIFE. As a consequence people who dislike Undertale truly ARE idiots - of course they wouldn't appreciate, for instance, the humour in Papyrus always craving attention, which itself is a cryptic reference to Shigesato Itoi's RPG epic Mother 3. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Toby Fox's genius unfolds itself on their computer screens. What fools... how I pity them. 😂 And yes, by the way, I DO have an Undertale tattoo. And no, you cannot see it. It's for the ladies' eyes only - And even then they have to demonstrate that they're within 5 playthroughs of my own (preferably lower) beforehand.
