BD does not have any passion for his game...He simply does it because he knows that he can make money from it...It's that simple and that is the reason that he does not quit it...
I can't believe I'm going to say this friend...
At first BD worked at a good pace, I won't say the best but it's okay.
After some time and this is completely my speculation, the guy got burned out on the game development, and literally left for something like 2 years, honestly it's not something strange that happens often when you focus on a task and don't give yourself time to take a breath.
After that he came back with a lot of encouragement... Honestly too much, he made very ambitious promises, if I remember correctly he promised 52 updates in a year or something like that... in addition to the supposed re-elevation of season 1.
The problem? He didn't keep his promise, he tried and had a decent pace after years of not working on it, but it didn't last long and it happened once again that he got burned out, and we are as we are today inconsistent but wanting to continue working on the game but without finding his way to do it well.
Add to this an endless number of excuses, lies and a complete lack of responsibility and no, I sincerely do not believe that it is because of the MONEY that he is not working properly, rather it is the money he earns that allows him to sink into that hole called "burned out."
