So, now that the dust has settled, could someone explain the appeal of this to me? I remember back when it came out everyone here and elsewhere were losing their shit about it. I got it recommended and gifted to me by a chum but it never really clicked with me. I did play through earthbound back in the day and loved the atmosphere and characters, but just found Undertale annoying and "sissy" if it makes sense. I played through it, I can appreciate the weird and innovative combat system, or lack thereof, and some of the jokes like naming characters after shitty fonts, and making them speak using them.
What I never got, though, was how much rave was there about the story and characters themselves.
What am I missing, /v/? What made this thing click with you?
