Final Fantasy II : See above
Final Fantasy III : Just played the NES version. Didn't get very far.
Final Fantasy IV : Played as FFII (FFIV Easy Type) through about 2/3rds of the game using an emulator. Brought anthologies recently and is now playing that (See Sig)
Final Fanatasy V : Played the FFV Rom, got to the Third World. The played the Anthology version. Got pissed off at Faris' speech. Guh. ^_^
Final Fantasy VI : Played FFIII Rom. Got V close to end on the PSX version....
Final Fantasy VII : Completed once, including getting all master materia twice, KOTR, Beating Ultima, Emerald and Ruby weapons.
Final Fantasy VIII : Completed twice: first time i didn't do Chocobo World, Doomtrain, Omega, Ultima and Leveling all Characters up to 100. Second time I did.
Final Fantasy IX: Completed Once, before I actually had a PSX (used ePSXe to play the entire thing through... v nice as well...) Did everything except Excalibur II...
