The only things I know about Touhou, because I am not a Touhou fan:
1. A lot of the things I've seen on the Internet, I later find out they originate from Touhou in some way, shape, or form.
2. There are a lot of "anime girls", which is normally something I like, but for some reason I either don't have an interest in Touhou, or I am too lazy to try getting into it. I haven't figured out which yet.
3. The Touhou games themselves are part of a "bullet hell" genre, where you need to dodge an insane amount of bullets at a very high speed in a short amount of time. Given my experience of dodging bullets while playing Undertale (which took a lot of time for me, because I mostly just play FPS games), I wonder if Touhou's bullet system is more difficult or is it easier than Undertale's?
4. Touhou originated on an old Japanese computer called the "NEC PC-9801". I knew about the PC-9801 for a while, but only because both Wolfenstein 3D and Doom got ports to that particular computer.
And that's all I can think of right now.
