How about just a sucker because you don't accept this behavior anywhere else.
How do you have direction when you keep adding elements, changing plots, and ask the audience what to do next? At some point he'll grow bored and give up when the money train stops, life gets in the way, or perhaps y'all have filled his retirement coffer just right and he can just ghost.
His unwillingness to hire anyone to help with art boils down to milking. Every artist had assistants. Marvel, DC comic, Disney, etc, they all use multiple artist on every project. It happens every single place where art work goes on. DC's just greedy and he knows it. He says he worked in the gaming industry than he damn well knows this is how it works. People can mimick a style. There's people in the fan art page who prove it. DC ain't a unicorn.
I'm tired of being feed a lie and being told accept it. I can't continue to reward this purposeful bad behavior. If you want to, that's your right but don't be mad when all you have is emptied pockets and a half finished game.
