1: I "found out" per se by playing touhou songs and covers in osu!, which was a game that a friend of mine introduced me to. At the time I didn't know what touhou was, so it took me a while to actually go take a look. My first interaction with a touhou game wasn't one from the original series but rather the fangame Touhou Luna Nights, which is that Sakuya metroidvania. I only got to play koumakyou a while later (th06)
2: Tough question because even though I took interest in Touhou, I never really was a fan of the games themselves, so I didn't play many (also because I'm just ass at shmups). All I can say is that Legacy of Lunatic Kingdom makes me wanna hit my head on the wall. Oh wait true uhhhh I like Antinomy of Common Flowers, even though it's not a shmup
3: You'd think I'd say Luna Nights since I just said that it was my first real contact with the series, but no. The answer is: none. I have a uncanny ability to just not pick favorites on anything, games included. Not saying that all the fangames I played (which were many, thanks to Moriya Shrine) weren't enjoyable, but that I can't decide which one was the best. Touhou Endless Dream and Touhou Hero of Ice Fairy are 2 excellent games tho.
4: Probably one of the reasons many people stumbled upon here: a convenient way to get the games while being sure it's not infected with a virus or something. (I took a while to find it though... google just didn't seem to want to show me the page goddamn)
5: That's another tricky one because even though I said I took a liking to some people, I don't think I've ever truly established a friendship. Like, I didn't go out of my way to go talk to people and all that, probs because I just don't have that much to say, and also because I suck at initiating conversations (as you can probably tell by my lack of activity here). I think the most I can get off with is saying CountVonNumenor because they're just all around interesting. If I'm to be really cheap I can just say flowwy cause he's my friend and he just didn't interact lol
6: Brings back the favorites thingy but this time I guess I can cite some: osu!, CS, the Yakuza series, Call of Duty Black Ops 2, Dark Souls 1 (was my favorite ever a long time ago, not so much today), Borderlands 2, Doki Doki Literature Club, A Hat In Time (this one might just be my "favorite" ever), the Tomb Raider series, TF2, Terraria, the Worms series, ULTRAKILL and probably many more I'm just not remembering right now.
7: food: yakisoba (cheap, filling, tastes great and easy to make) // drink: water (second might be some good old coke, but I've been drinking less often) oh yeah also wine and all sorts of alcohol except for beer // dessert: idk lol probably just some good old icecream // sweets: if we're talking anything here probably the holy chocolate bar known as hersheys cookies and creme (I love eating fake chocolate with crunchy cookies)
man this took me a while to think about, thanks for the questions! ᗜˬᗜ
