I have various memories of encountering Touhou in general before getting into the games, but I can't really put them into a clear order. I'm pretty sure Super Marisa World and Mega Mari were in there somewhere, and I probably heard some Touhou music without realizing it, but it's all rather hazy.
I have two somewhat more distinct memories of seeing the actual Touhou games, though I'm not sure which of them came first.
Back in 2010 or so, I used to play Mario Kart Wii a lot, including doing competitive Time Trials. Some of the members of the community were also into Touhou, so every now and then, they would put Touhou music in their videos. One such video that I watched used Flandre's theme, U. N. Owen, in its original form and gave the name of the track. The music interested me enough to make me want to look it up, and that led me to a video of EoSD's Extra Stage. I remember being both impressed by the apparent skill demonstrated by the player and rather confused by the dialogue. (I believe it was Marisa's scenario, which probably didn't help.)
The other memory is more straightforward. I've been following the Youtube LPer RoahmMythril for quite some time, and while he's best known for playing Mega Man, he's also dabbled in Touhou a bit. In
one of his old videos, he showed off some of his StB replays, and while I had no idea what the game was at the time, I watched it anyway because of who was playing it.
Roahm also gave me my first proper introduction to Touhou a couple years later, when he did a full LP of IN. He explained the mechanics as he played, and since he was only playing on Normal, the game looked doable enough. I think I can safely say that it was because of that LP that I finally bought PCB some months afterward.
My first hands-on experience with the game consisted of several hours of frustration over the installation, but I eventually found everything I needed and got the game running with the English patch, though I ended up using AppLocale unnecessarily because I hadn't changed the Japanese folder names. I also didn't know about the VSync patch back then, but I started out on Easy mode, so it wasn't too bad. Even on Easy, though, I needed continues to finish the game; everything from Stage 4 onwards was difficult for me, and Resurrection Butterfly seemed utterly impossible. I kept practicing and trying out different shot types, though, and a few days later, I managed to
1cc Easy using Sakuya A. I quickly moved on to Normal mode, and a few more days after that, I got my first
Normal 1cc (albeit with the help of extra starting lives; I had also used them in my Easy 1cc, but I finished that run with 2 extra lives anyway). It wasn't until several months later that I got around to
clearing the game with the default number of starting lives, and by then I had already
cleared the Extra stage and started working on the Phantasm stage. Both the Extra and the Phantasm stages were major challenges for me, and even after I learned how to deal with Ran, Yukari still gave me a lot of trouble. However, I kept working on the Phantasm stage on and off, and after enough attempts, I finally managed to
clear it and felt quite accomplished for having done so. (Little did I know at the time how much easier it would have been with VSync. :derp:)
Sorry for rambling on for so long... Writing all that did take me on a nice trip down memory lane, though, so thank you for that.
