Storylines, I'd leave them as they are, characters too, settings, well, for FF8, I would change the Junctioning system cuz it wasnt that good, and cutscenes were all awesome, leveling up and experience gaining was overall great except for FF 8 and 10, 8 because it was too easy, 10 because they abused the lvling system. I wasn't really disappointed in any FF game, they are all good overall.
