Maybe he hopes to return to Bioware and doesn't want to burn any bridges.
It's not like he enjoyed success after leaving the company.
This. Being successful in the industry is all about maintaining your connections and being with the "in" crowd. This is why everyone sucks each other's cocks and why Twitter looks like high school for gamedevs.
There is a downside to that - these industry leaders appear to have believed the market would be accepting and completely woke at this time. That's why I'm guessing there have been so many catastrophic failures - these games take a long time to make, and there may have been an assumption 3-5 years ago the ticket to big, big sales was a diverse staff and ugly troon chars. It became part of the design and it's shown to have missed the mark. Biggly!
David Gaider is way off the mark on where your head should be at to produce a big seller. He's doubling down on what worked in the distant past, but its obvious his mindset is not in line with what sells. Some studio hires him, they'll get what isn't working now. Who would want that, as from all his online postings he seems unable to correct his approach?
