Founder of western console warring.
The psx was exclusively a 3D machine it had no 2D hardware. It just that 3D in 1994 for under 400 dollars had to have compromises made. Having a FPU and a Z buffer and support for AA, trilinear mipmapping etc... wouldve cost thousands of dollars.
Whatever the reason, to me because of this the N64 graphics were far superior.
I mean ps1 couldn't even do stable 3d...
