I don't think Destin (Smarter Every Day) is a single-person team, but he's making $6.8k/video, with two videos per month.

Patreon seems to work out for smaller-scale projects, like youtube videos or podcasts. Its a bit harder to map it to a video game, but I still think the Patreon model for video games is superior to Kickstarter.

Everything is crap though, some real innovation should happen in this space. Unfortunately, I'm out of ideas...
