I was in the same boat and stumbled on Dawncaster. It’s the best mobile game I’ve ever played. I’d honestly play it on PC too, but it’s strangely mobile only. You could compare it to Slay the Spire, but I have found Dawncaster much more satisfying and fun for me personally. Also very active devs who are opposed to micro-transactions.
Live content has lots of downtime and dull gameplay moments. It can’t compete with polished, edited videos - except in the one area it shines: human interaction. That works better when you can see the person. So most streams feature a person or at least an avatar, while edited videos often place a higher emphasis on gameplay. Each format is simply playing to its strengths. The ones that don’t you rarely see because they’re buried at the bottom of page 726 with four views.
