1. When did you get into Touhou?
C. Second section of Windows Era (10, 10.5, 11, 12, 12.3, 12.5, 12.8, 13) ~ 2007–2012
2. What made you first interested in Touhou?
B. Secondary works (fangames, music, manga, and art)
I saw Momiji art online and I was intrigued. Pls don't judge.
3. What made you stay with Touhou?
Games are fun, music is great, fanbase is more dedicated than any other I think I've ever seen.
4. What level of fanbase do you like to interact with?
Both medium and majority.
5. How familiar are you with Touhou lore and story?
B. Average (only know about some character backstories and some story of games, but not to the point of remembering everything)
I'm familiar with a lot but I can't always keep track of it all.
6. Do you think Touhou is the hardest bullet-hell game?
Probably not. I don't dabble in many others outside of it, but games like Ikaruga and others are challenging in their own right.
7. Do you think Touhou Gacha harmed the franchise?
Maybe? I don't interact much with TLW fans (since I can't stand gacha games) but I feel it's a poor introduction to the world of Touhou, just like how FGO is a poor introduction to the world of Fate.
Touhou isn't and never was a gacha. It's a bullet hell. Only knowing or caring about Touhou through Lost Word is pretty disappointing.
8. Is piracy within Touhou good or bad?
3. Other
I think it's somewhat bad. I'd like to support our lord and savior ZUN but actually buying the games, especially in English, isn't very easy. Piracy is a necessary evil in this case since it's really the only easy way for a westerner to get their hands on Touhou.
9. How flanderized do you think Touhou characters are?
C. 5–6 seared, but not charred
Some are more affected than others, I reckon. For example, I think Marisa Stole the Precious Thing has forever smeared Alice as a totally smitten lovebug for Marisa, when that's really just fanon. Yeah, it's fun; the fanon personalities of characters give them even more life than they do in the games. But it's flanderization nonetheless, I suppose.
10. Overall, which era(s) did you like/dislike the most?
PC-98. Don't bash me for this. The games are good, but I reckon the Windows games are far, far better.
As for like, you can't go wrong with the first Windows era. They're classics and most peoples first introduction to Touhou anyway.
