That's actually the sad thing. DC found the easiest way to squeeze the money out of his patreon supporters. Why change the model on which he could earn money.
Sustainability. "This is making us lots of money" =/= "this is always
going to make us lots of money."
If you wait until your cash cow dries up, it's too late. It is 1,000 times easier to start something new with a huge existing fanbase than to earn
back your fans - for your current project
or a new project - once you've run your reputation into the ground. And that's exactly what's going to happen. It won't be a huge, sudden crash, but I guarantee he's already started slowly bleeding patrons. That trend is going to increase.
Smart money is to begin a new project when you're getting close to finishing your current game. Star talking about being in the home stretch for your current project. Lay out a "road map to the finish line." And while you're hyping everyone up for the new release, simultaneous start talking about what's
next. Use the buzz you've got going for your current project to get an accelerated launch on your
new project.
