So in your opinion, when exactly should a creator start a Patreon or Subscribestar?
From my perspective, every game creator has their own vision, but of course they don't know if others will support this project, so if in this case they haven't created any games before, how would they make money?
Imagine that a game creator quit his job to focus on his project, he decides to publish his first version of the game and does he really have to wait a few months or maybe even years until the game is finished and only then he can start his Patreon?? You need to explain more why you think so. Looking at our forum, we know perfectly well that it's not true that you have to have a game on your account to open a Patreon, a good project/demo will gain support quickly if people see that it has potential.
