The 90s gaming golden age was propped up from the bottom with highly talented and sincerely motivated game devs/designers/programmers/artists.
Brian Fargo was one of those guys.
Fargo trying to find a scapegoat to punish for the delay is just him trying to cover up his own management failures.
How was it Fargo's fault that Fallout got delayed? He put Tim in charge.
And dishing the punishment an Tim because he stood up for his team by not revealing the culprit is nothing but spite.
Yeah, that's what bosses do. Some 20 years ago, I knew a guy who was one of the most productive employees and his supervisor liked him. He hated the time-wasting meetings he had to participate in and made a bunch of jokes in one when it was his turn to be in charge of minutes. His boss's boss didn't like that and told him he needed to be more professional. My pal had a bit of a chip on his shoulder and said no. They immediately fired him for insubordination and had security escort him from the building, his productivity and good work didn't matter. Most of the states have at-will employment and you can leave or be fired for any reason at any time. Fargo would have been within his rights to fire Tim for saying no to him, and there are plenty of bosses who would have, but Brian clearly valued what Tim had to offer. In hindsight, it would have been better for his ego just to fire him since the outcome would have been the same.
