I see what you mean about the ending of FSN, I agree it did show how central to the core those principles were to Arthuria, however given the emotions the writers had tried to add as the series grew, whilst sacrifice was also core to her character, a reward in death/slight glimmer of happiness in the epilogue would have been a slightly more...fulfilling ending IMO, whereas the normal ending almost implies that no matter what you sacrifice and how strong/wise/etc you become, it'll never be enough. The whole last episode thing for the PS2 edition carried that off, without interfering with the current ending. Guess thats just me though, a bit of a sap for a love story
