TL;DR: Less is more
Although antis should be burned alive, I do admit that her streams would be more enjoyable if she didn't play 37 different games at the same time.
Recently there was a point when she was playing FFT, Power Pros, Digimon and Pokémon all in the same week. Not to mention the extra sponsorship streams sprinkled around.
I can barely immerse myself in 1 game while doing college, internship, study and watching streams. So I believe she would be able to put out a better stream if she tried focusing more on at most 2 games a week.
I watched streamers on Twitch since 2012 and the tradition was always to play 1 game until it ends, so I don't really fancy the strategy of playing multiple games at once
