Garnet: FFIX definitinely, it's recommended you give old-school games(FFI-V) a try first to understand that the sidequests and items in FFIX are all mainly tribute to the past, I'd also recommend you play FFVI thru FFVIII later, because basically those three games pulled away from the way a Final Fantasy works, it went into a bizarre science fiction setting most old-schoolers never could understand, likewise, old-school games and FFIX yield a fairytale setting new school gamers that began playing FF with VII don't understand.
