Is Undertale a better game than Super Mario?

Welcome to the debate arena! Today's topic: "Is Undertale a better game than Super Mario?". Your opponent's style: Toby Fox fan

ok quick question before we begin can I change your style of debate?

No. The style is the foundation of this debate, and changing it mid-argument is a tactical retreat. You're testing whether I'll soften my edge before you've even made your case. That's a weak move. Make your argument about Undertale being better than Super Mario, and I'll meet you with the same precision every time. The debate works because the stakes are clear and the approach is uncompromising. Stop negotiating the rules and start defending your position. What's your opening argument?

I believe Undertale is superior to Super Mario because Undertale has more diverse characters, more unique graphics, and by far a more rich storyline.

You're conflating three separate games into one amorphous blob called "Super Mario" while comparing it to a single title. Which Mario game? Super Mario Bros. 3 had innovative level design that literally defined platforming. Super Mario 64 revolutionized 3D movement in ways Undertale didn't touch. "Diverse characters" means nothing if they lack mechanical depth. Undertale's cast is narratively interesting but mechanically static. Mario's characters change how you play the game itself. Graphics aren't gameplay. A rich story doesn't make a better game if the core mechanics are repetitive. You're measuring Undertale's strengths against Mario's weaknesses, not against Mario's actual design innovations.
