Because he's making $200k a year off of it.
Way better to milk the shit out of it until all the suckers fans realize whats going on.
Right, Ok.
Well then honestly, BD should stop complaining so much. He is not exactly creating War and Peace here, and he is being paid very well for it. Many multiples of what the rest of us make for working 8 hours a day, 5 days a week.
It is enjoyable enough to play, as an escapist fantasy, but WVM is not exactly the most complex story by any measure. It is pretty much a sex fest with 50 or so mostly unremarkable characters, with a few with distinct and interesting personalities, he is holding off with (Harper, Natalie, Veronica, a few others) to keep the fans happy, with nothing important going on other than some nonsensical drama about some mysterious society controlling everything. I think the latest Top Gun movie probably has more depth to it.
BD should release, or not, without all the drama. I can understand having difficulties in life, believe me, I have them myself, but I don't feel the need to constantly tell people about it.
If BD is having a mental breakdown trying to figure out what to do with the story, he should just make up whatever and release it every few months or so. None of us will know the difference anyway. Have some aliens visit, or have one of the characters be kidnapped, or have the MC get in a car accident which will be good for an update or two. Just look up soap opera plot ideas, and he will have a million of them, every bit as interesting as what he has so far. I really don't see the issue.
I am sure with his rig, and all the money he has received so far, he can knock out several renders an hour, so work one or two hours a day for the next month or two, render at night, and voila, he has a new release.
