# Making a game is too much of an effort (time, overhead,... ), even as a hobby, to dismiss proper monetization. Money is king. Here and everywhere.
Many devs, if not most, start renpy games as a hobby because they love some of them, leaving to fate what will happen next. Big Brother was an inspiration to many.
But once they're successful, and OGrey is off the chart, none of them walks away from driving fans to his funnels. He'd be the first one. A saint (aiming for utopia), stupid (rejecting sure and deserved money) or a flake (simply being quirky or weird).
It has nothing to do with leaving his job. It's about having multiple income streams, doing what they love, as people nowadays should. Let's agree to disagree.
