I have a PS3, but its a backwards compatible model so I have kept a lot of my old PS1 and PS2 games, my favorite PS1 platformer is the Spyro the Dragon series. I also enjoy Blood Omen, Soul Reaver, GT1 and GT2, and Rogue Trip and even though the graphics are not nearly as good as PS2 and PS3 games they are still fun to mess with on occasion.
