Great games that aren't replayable

[xenogears1234]

A lot of the longer rpg's cause sadly i just cant invest 60+ hrs and then down the line turn around and do the same title over. Especially since by the time i finish said titles, the story is known and the gameplay mechanics/leveling system have been played to completion, and unless there is some post game/new game mechanic as an incentive i just move onto the next game.
