People bringing up Touhou again? It's always interesting when people bring it up at least. I won't say it's "Dragon Quest" levels but it's more like Banjo-Kazooie levels, maybe barely higher due to Touhou having more games.
And honestly Touhou is a rare Indie series that has been around since 1997, making it one of the, if not the oldest Indie series around. I can't think of many more indie games or series that have been around that long. And the fact that due to ZUNs relaxed copyright made it into one of the largest Doujin series around essentially made it a bit of a pop culture thing in Japan, at least when the Windows era games blew up. Hell, a lot of would-be developers got inspired by Touhou, including the likes of Toby Fox and even former Nintendo developers worked on a few Touhou fangames.
It's always a treat seeing it being discussed in Smash and not treated like this "Unknown Boogeyman". I still think Reimu or any Touhou content is still possible, especially since ZUN seems to like the idea and literally all it would take for negotiations would be Sakurai giving him a nice, cold beer(I wish I was exaggerating or joking about this) which makes Reimu, compared to a few other 3rd parties that are brought up very easy to negotiate on.
The only question is if there'd be interest in Nintendo and Sakurai for anything Touhou related in Smash or not. But it's good to see support for Reimu and Touhou have been gradually building up recently.
