The playstation was hardly instrumental in establishing 3D games as .. actually VIABLE alternatives to gaming. 2D was still in style back then.. but until a certain few games that all arrived at the same time.. 3D platformers didnt exist.
Crash Bandicoot SCEA 08/31/96
Super Mario 64 Nintendo 09/26/96
And starting a full FIVE years after the fact, the birth of the NEXT GENERATION of platformers. The bar is constantly being raised even now.
Jak and Daxter: The Precursor Legacy SCEA 12/03/01
Ratchet & Clank SCEA 11/04/02
Prince of Persia: The Sands of Time Ubisoft 11/06/03
God of War SCEA 03/22/05
With noticed mention of certain games that just wouldnt be the same if someone hadnt shown the world how a proper 3D game should play:
Metal Gear Solid Konami 09/30/98
The Legend of Zelda: Ocarina of Time Nintendo 11/23/98
Soul Calibur Namco 09/08/99 (Previous 3D fighters being.. what? lol)
Devil May Cry Capcom 10/16/01
