I'm talking hardware here. I didn't say Sony invented 3D games or even 3D hardware, I said they did affordable consumer 3D hardware first, ahead of anybody. Yes Wolfenstein and Doom and Hard Drivin' exisited, but 3DFX and Nvidia were nowhere in sight in 1994. Sega and Nintendo weren't thinking about dedicated 3D for their consoles, and Sega was using Model-1 and Model-2 hardware cost 10s of thousands of dollars and didn't even do everything in hardware, despite the crazy price. Like I said before, it wasn't until 99 that Nvidia finally brought out the Geforce and did everything that the PS1 did, even though by then it did some things a lot better.
And 3D on the Saturn was definitely an after-thought. It didn't even draw triangles, it drew quads (squares), primarily so they could use it to draw scaled and rotated sprites head on. It had dedicated hardware for drawing multiple BGs, but not for transforms or lighting or shading or blending. At best they expected 3D to be an abberation. After they got wind of the PS1 Sega added an extra processor and DSP to try to replicate what Sony's GPU did, and we all know how that turned out.
Credit where credit is due, the PS1 shook things up huge.
