How did Undertale get so popular? This is a genuine question. What aspects about it made it reach and resonate with as many people as it did? Why do other similar games fail to achieve even a fraction of its popularity despite doing some things "better" or more refined? A lot of people say it's the memorable and iconic characters, music, and design philosophy, but what exactly made those things memorable and iconic in the first place? The whole thing is really fascinating to me, and I want to understand how the stars aligned to make this happen.
