First PlayStation is called "PSOne", not "PSO". Next time before you decide to make cuttings like that, think trice. "PSO" is a well-known way to cut the "Phantasy Star Online", using such acronym for anything else but just Phantasy Star Online itself is a wrong thing to do. Better not do that again from now on, mate. It confused me heavily enough, do not think someone else wouldn't be confused either if you continue on doing that. From this point on, if you want to call the first PlayStation in a shorter way, say PSOne (NOT PSX - that is wrong also), just like everybody else does.
I play these anytime and at any place: "Guitar Freaks" series, "Silent Hill" series, "The King of Fighters" series, X series, DDR.
PS1 - Final Fantasy VIII PS2 - Oh, god, I can't really remember anymore, it's been so long and I've had so many. I think it might have been DBZ Budokai.... PS3 - Technically, Tomb Raider, as I put it on layway along with my PS3, but Final Fantasy XII was bought outright, and so paid for and brought home first.
