Well, to be fair, CVN, like I said last night, I think most people undoubtedly get into Touhou through the music and the fangames - I certainly did with Wandering Souls, which was an extremely impressive combination of the two for sure. Granted, some people will come in because of the artwork, and yes, even material of an adult nature, but I highly doubt it's as high as 99%, probably not even a fraction of that. (^_^)
I mean, 'Bousou-Get!' may have been the very first real Touhou inspired work I ever came in contact with, yet truth be told, beyond knowing it features Reisen & Eirin, I couldn't tell you much else about it since I've never actually read it. No, it was over 5 years after that before Estheone's game turned my head enough to get me into the series, so it just goes to show you how little influence H material really had on me back then. (^u^)
Hmm, and that thread you cite regarding the Nature of Gensokyo looks like pretty heavy going too, but I'll check it out when I have a moment. (^_~)
