Bethesda dropped the ball not adding multiplayer to their Elder Scrolls games, even after it was heavily requested. Then they turn around and help create an MMO with even worse gameplay freedom as Skyrim that butchers the lore even further.
Rockstar dropped the ball pissing off the PC market twice (still no Red Dead). You're not giving the people who made the Euphoria engine enough credit for Rockstar's success. They share equally as bad practices. ($$$)
Having both these companies combine would be equally as devastating as Capcom combining with EA. Day-one DLC MMO with in-game advertisements and shoehorned gameplay.

They normally don't. Namco-Bandai made the PC port.
From are console developers. They enjoy it. They don't care about PC master-race nonsense.
Although... I can't support what they're doing to the Armored Core franchise.
