I’m really surprised at how bad of an experience people are having! I have a bunch of channels I follow and people I interact with. Some big channels but most small. I love channels with only a few hundred to a few thousand viewers. The creators post their videos and then I talk to them through the comments. We have some really interesting conversations.
Lots of other channels I follow I don’t interact with but still really enjoy. A lot of hobby channels are amazing! I generally avoid the news and politics stuff, though I still occasionally watch Ukraine videos or Trump trial stuff. I get sick of those after one video though!
And that’s the most naïve way of looking at it. With more data you may be able to see if Linux users favour certain genres of games over others, so the number may be a lot higher than 2% for your game in particular.
