The gaming industry of this genre needs some kind of common platform like patreon, but with strict control from the owner of this site itself. Patreon, using icstor as an example, can only occasionally inform people in some way that this artist is not in a hurry to release new content, but this does not work quite the way the patrons would like.
There is no quality control and execution of a predetermined development plan.
If patreon were a guarantee that an artist wasn't just milking his patrons, but that he would actually release the promised content on time - I'm sure that would scare away artists like Dr. Banana and they would have no choice but to settle for the little things of some brainless fans.
For really good artists who honestly work off donations and delight us with their work in reverse, this would attract new patrons and thereby create a larger project or speed up the development of the present one.
Started to be lazy and endlessly postpone the release of the update? Please go to the conditional Subscribestar.
As long as the very concept of a patron implies blind support, there will be an infinite number of such artists who do 1 interesting project, 2 or 3 good updates and then just go inactive and enjoy an endless stream of donations.
