PS3 literally got revived due to KZ2, Uncharted 2, GOW3 all of which were the best looking titles that generation taking the crown back from the 360 that started strong with Gears, Bioshock and other third party games. PS3 was ultimately defined by its boundary pushing exclusives. That led to its success in the PS4 era with an insane reveal of KZSF, DriveClub and Infamous back to back. Infamous literally fucking started the photo mode craze. The infamous E3 2015 and E3 2016 conferences that literally started the death of Xbox and sent PS4 sales to the stratosphere were all based around multiple boundry pushing graphics that were simply not on the Xbox or Nintendo.
And PS1 and PS2 were both trashing the competition because despite the hardware disadvantage, the best most boundry pushing games were PS1 and PS2 exclusives. RE2, Tekken 2, MGS, GTA3, FFX, MGS2, DMC, the list goes on and on. They didnt have to make their own exclusives because they just bought them back then. PS3 is when the Sony first party finally found its footing. before that they didnt have to invest in anything.
