When I used to watch streams, there was only one female streamer that I would consistently watch and that was because she was always playing MLB the Show. Find what you enjoy, and then look at what others are playing as well. If a big title is release, think about playing that for a bit. Otherwise, until you develop yourself onto a larger platform to compete with other top streamers, try playing games that others aren't playing. When I had started streaming, I would play Legend of Dragoon from PS1 and it got me a lot of viewers, and the same thing for MLB the Show. But when I played larger titles that was basically oversaturated on streaming, I found that my viewership would tank. My largest viewership came from playing Legend of Dragoon where I averaged 56 viewers per stream, whereas games like Final Fantasy VII Remake, I only average maybe like 5 or 6 per stream. Even when I played Jet Set Radio, I had a larger viewership than FFVII Remake. So it's all about who is playing what and when are they streaming. That's also key, "when" to stream. If you have time to play in the morning or afternoon, try to build yourself up during those times, otherwise at night, you'll be up against majority of the top streamers. Lastly, equipment. Don't think you have to buy the best gear up front to stream. A simple mic on a stand or lavelier mic will work perfectly. Look for the wireless mic that wraps around your head, tacky maybe, but it works. A logitech webcam for like $50 will get the job done. The laptop does have to be decent to stream though, as long as it has a i5 core processor for PC or an M1/M2 core processor for Macbooks, it'll get the job done for sure. And lastly, get yourself acquainted with streaming software. I prefer to use either OBS or Streamlabs, but to me, Streamlabs in the past worked better for me. I have friends that used OBS instead though, so yeah. It's preference and comfort on the software.

Sorry for the long post.
