I am still tripping balls at how extremely popular Undertale became in Japan, from being referenced in anime/manga like Pop Team Epic to making Sans be a top 3 Smash ballot character in Japan (for better or worse, I guess), and even get the game released on the Switch, for Christ's sake. I wonder if Japan's uncaring attitude towards "bad fandoms" played a big part on that.

Whatever the case, mad respect to them, and big kudos to Tobyfox for doing an almost impossible feat: break grounds with a Western product on a country known for doing the same on every other country in the world while still remaining mostly uncaring about outside influences, instead prefering their own stuff. Most AAA brands can only dream of learning how to replicate such a pattern, and this dude did it mostly alone with Gamemaker, a Kickstarter account and a dream. I think I am starting to understand where his "determination" theme came from, because his story truly is an embodiment of that and its pay-off.

You sound less than thrilled about that, like you're gonna have a bad time when it happens.
