Personally I feel the PS1 was Sony's fluke system, that got its big break more on flashy advertising and upstaging the Sega Saturn more than anything else. There was a lot of shovelware made for it and it had a lackluster launch library, but hey, I'll give credit where it's due and things eventually got better. I did own a PS1 and an N64 both in their heydey and I feel more attached to the N64 than I did the Playstation. Goldeneye and Perfect Dark probably had something to do with that, but again, the PS1 was no slouch.
Nothing really compares to the runaway success that was the PS2 though.
