>>68627441>>68627792I can't believe your thread fucking died before I came back. Rude.
Anyways, I don't know anything about you so I'll try to make this detailed enough to be useful but also general enough since I don't know exactly what you're looking for. Let me know if you have any questions.
>Market sizeThis post is going to be primarily about Touhou games, since I'm most familiar with those, and I'm assuming they're what you had in mind as well.
The first thing you need to accept if you're going to specialize in danmaku is that the current market size is pretty small. A really good player like Yatsuzume (male, non-vt) can get around 100 CCV when going for a huge goal. The Touhou World Cup event (the biggest happening of the year for Touhou players) gets around 500 CCV for its English broadcast (but a lot more in Japan & China). Popular streamers can get good or even slightly above average numbers streaming Touhou (4 to 5view range) - like grayfruit, beatMARIO or the few holos who've played it. But the average nobody streaming in the Touhou Project twitch category will get a couple dozen viewers at most (many of those being experienced players watching for the category, not necessarily for you). Still, for the most part, viewers don't come for Touhou but they CAN come to root for the person playing it. You'll need a likeable personality, some luck and a lot of creativity if you want to build a streaming career off danmaku games - in fact, if you could do that, you'd be one of the first people in the world to do it (second after Mushi if I'm not mistaken).
>Gaining the initial 2hu viewer baseThankfully, this is the easy part. People do watch and interact with Touhou streams just out of sheer interest for seeing a new person try them. Simply by having the category on your stream, you should start to see a few names that can form the start of your viewerbase and that'll keep you company in the 1view and 2view stages. Do some networking in the major gameplay-centric discord servers (#danmaku in the Touhou Project server, and the Touhou Replay Showcase community server (which has a #streams channel for shilling yourself) - there's a few others, but I believe those two are the main ones). Don't worry too much about being a newfag, unlike what 4chan might have you think, the Touhou gameplay community is welcoming to a fault and playing on Easy is fucking fine. You'll meet a lot of cool folks who can help you with pretty much anything you wanna try. Also, having your avatar/brand reflect your love for Touhou/gaming/NEETness would probably be a good idea, but I'm no expert on that.
>MushiWhat I've just described closely lines up with what VTuber Mushi did to start out. She's now a somewhat well-known indie with around 10k followers on both Twitch and Twitter, but unfortunately she moved away from being primarily Touhou-focused and she hasn't streamed in a while (she's currently mostly posting pics of herself on twitter, which I would really advise against doing as an oldgen vtubing fan). Still, if you could get in contact with her, her perspective on this would probably be invaluable.
>What to streamFirst time discovery and gitting gud at the games. Getting anything done in danmaku is inherently a big time investment, and there is a LOT to do - dozens of games to try and conquer, 4 difficulty levels to climb up, and many side challenges as well. Viewers will root for you and want to see you improve. Self-improvement is really the driving force for every Touhou player and seeing it happen in real time is deeply satisfying both for you and your viewers. Don't be afraid to hop from one challenge to another in this stage. You'll learn a lot about the series and the basics of dodging and managing your resources, while also bringing variety to your stream and prolonging the whole process (game-hopping is not optimal if your goal is just to beat a game, obviously). Make sure to publicize your first 1cc, it's a huge personal achievement!
Once your skill level and perseverence allows it, you can start going for high-level grinds. The kinds of grinds people want to watch: improving your No Bomb survival personal bests on Hard/Lunatic/Extra, getting a perfect Hard/Lunatic/Extra run, setting and improving your score PB on Hard/Lunatic/Extra (this one is a niche within a niche, so maybe don't), 100% completion of scene games, the No Items challenge in Impossible Spell Card (TH14.3)...
You can also vary your content with: fangames (danmakufu scripts, gamejam games, meme thcrap patches), other games (well-known non-Touhou shmups, Len'en, other well-known hard single-player games), non-game Touhou related interests (doujin works, drawing, programming, music-making, etc.), or really anything you want. Just make sure you're still mostly delivering what people are following you for to keep them hooked.
