What games, if any, do you revisit or replay often? I usually pick on people who are too in love with retro games, but even I have my old school guilty pleasure.
My game is Star Ocean: The Second Story.
It's flippin' amazing! There are like 16 playable characters, all of whom are not available on a single play through, but all of whom are great! It also boasts 50+unique character endings!
I bought this game twice on PS1 and I just bought it again on PSP (a slightly updated version.)
This game has a god-tier combat system. The special moves (of which there are over 100) each have animations that "evolve" as you continue to use them. The drastic visual changes are something I have not seen repeated even in later entries of the series. The game truly stands out on its own.
