It's not even close, PS1 ftw. OK to be fair the first year or so of the PS1 wasn't great, but after things got going they really got going. I'll take FFVII, FFT, Vagrant Story, Chrono Cross, Parasite Eve 1 and 2, Legend of the Dragoon, Metal Gear Solid, Twisted Metal 2, Tekken 3 ect ect ect over any other systems line up. The last 3 or 4 years of the PS1 were just unparalleled for awesomeness, especially on the RPG side of things.
Square made a few good SNES games but really outdid themselves with the PS1 once they had more room thanks to CD technology. The change in presentation and scope on the PS1 was just immense. Voices, CGI, huge game world, graphics that don't look ridiculous in hindsight...
I mean I liked the SNES at the time and all, but nothing compares to the out and out dominance of the Playstation (not even the PS2).
