Nope. All companies started in the 90s as groups of gamerbros. When they started to make loads of money and had to get managers cause they didnt want to do management was when it started to go down.
That’s really not at all what happened. Gaming development goes back to the 70s and gamerbro culture has almost nothing to do with history of game dev, that’s a more recent thing that happened with DOTA and the like.
Blizzard made awesome games and was led by someone who wanted to make awesome games. Eventually they gave upper management to someone who doesnt play games and now we have empty sheels
