I don't know about that particular game, but some of the games have options to make them quicker, for exactly the reason of making completion times more comparable across games. For instance, some of the supported RPGs have options to multiply experience and money, to reduce grinding, as well as options to shorten or skip long cutscenes, modify victory conditions (e.g. number of MacGuffins required), or add fast-travel systems to games that didn't originally have them.
