One of the things with Patreon pledges Dobby doesn't understand is they don't even have to be that big a thing, they just need to be SOMETHING. For instance take the guy who makes Dwarf Fortress. He isn't making porn patreon bank, but he's making a few thousand a month (hell he made around $3-4k a month on donations before Patreon was even a thing, current YTD is $22k), enough to support a lower middle/ upper lower class lifestyle just from making his one free game. And what is the backer reward? A crayon doodle or a short story set in your generated world. The point isn't that the work is quality (It isn't, I mean it's art by a programmer), but that it shows that you actually give half a shit about the people supporting your hobby.
The problem is to Dobby his art is all about him, not about his "fans" and the number of fans is growing smaller every day.
