The base game's character writing left so much to be desired they had to make an epilogue to give much-needed closure to its only decently-poised (no offense to bestest buddy Reyn, that's my boy), now fully fledged character, by means of a plot and cast that, unlike the main narrative, don't do the appropriately different themes a disservice along the way. The nod to Xenosaga is pretty neat, but future instalments in the series wouldn't be predestined had the base game truly been definitive.
