2d is such a muddy term anyway. include SRPGs and you've gotta include Diablo 2, which in my mind is 3d. then there's Warcraft. at that point I don't even know what 2d means. sorry, neon.
I'd have a hard time calling FF7 3d -- or any FF on the PS1, really -- but most people would differentiate between SNES FF and PS1 FF.
