Lord, this may take awhile... For the sake of conveinence, I'm ditching games with changeable job classes and Mon style games unless it has a limited party system (i.e. Persona...). Also, due to some games having you use variations of the party throughout the game, in some cases I'll be listing my party for the final dungeon. I also decided to list games I regulary play as opposed to ones I've played once and sent back to the shelf to collect dust.
