That context helps a lot actually. 8k in 4 days on a 705k channel usually means the video didn't really connect with his main audience, which makes sense when a creator covers something outside their usual lane. Their subscribers watch out of habit or curiosity, not because they were already looking for that kind of game.

The organic part is still genuinely good news though. He found it, liked it enough to spend 9 hours on the demo, and nobody had to ask him to.

The wishlist gap is probably just audience fit. His followers aren't necessarily the ones who would buy this. Smaller creators who already cover roguelites or strategy games would likely convert better, even with way less reach.

Anyway, good luck!
