You're right but that's not what I was referring to though.
But while we are talking about the 2 studios, I would of gave the GT franchise to the Evolution guys and axed Polyphony. GT is still big but imagine how much bigger it would of been if Polyphony didn't keep fudgy up.
I'm not sure but I remember two different things.
DriveClub was not functional at launch, EVO needed at least 4 full months to fix everything in the game (coincidence at the same time MCC was launched full of critical issues too that took months or even years to 343 fix it)... it was a mess that did cost the studio life inside Sony.
GTS was launched lacking content but it was fully function... even today the core of the game is the same because PD never had to work on that since launch just putting post launch support in add more and more content... and that is where PD did the best... the post game support in GTS is something to be used as a case because they are delivering every month scheduled updated that add cars, modes, challenges, and tracks (not all months).
They are complete different management of Studios... one give no trouble to Sony while the others was a mess to support it.
Is it unfair? Probably but if you look at Sony they had no choice... EVO did that to themselves... they are talented but they had one of the worst development and launch in the last decade on pair with the crazy mess of MCC.
Of course if you see today games launching like Anthem, Fallout 84, etc you will remember that low quality releases started with Battlefield IV, DriverClub, MCC, etc.
