This is an old problem, but still, Neuro/Evil solo streams are ADHD responses to donations from the chat. All this leads to the fact that the sisters rarely get hung up on any topic for more than a minute, usually then forgetting about it for the entire stream and never returning to it again.
The cool thing about "real" streamers is that they can talk about one specific topic for a long time and can come back to it if needed.
Imagine a situation where Neuro is asked who her favorite Pokemon is, but she doesn't just say that it's Shinx, but also asks the chat who their favorite Pokemon is, after that she starts commenting on their options, explaining why she thinks Shinx is better, arguing with the chat who is stronger Pickachu or Shinx, etc.
The coolest option would be if Neuro could create such topics for discussion itself. And these could be different ways she came up with some of her own stories, current news (for example, the victory of the England team or the release of a new film), events from the past (for example, past collabs), etc.
I understand that it will be very difficult to implement something like this, but as much as I love Neuro, listening to streams that are largely the same in structure is becoming increasingly boring. And diversity in the form of games or small segments, although it improves the overall quality, does not change the overall essence. All this leads to the fact that, with rare exceptions and outside of collaboration formats, Neuro/Evil has practically no room for creativity.
But discussion of topics from Neuro/Evil would improve not only the variability, but also the situation with communication with the chat, because for a long time now it has been primarily a spam of smiles with a rare full-fledged discussion of anything, and so the chat will have more reasons to communicate with each other and specifically with Neuro/Evil.
