If I could go in full blind no prior knowledge? Final Fantasy 6. I get that it's cheating but it was a sprawling emotional epic and it's been twenty years. I remember getting to the end at like... 3AM after basically a full complete and maxed out run and that ending was.... I want to say a half hour. It had a hell of a lot of emotional callbacks, resolutions, and a few genuinely funny moments. All in a refutation of Kefka's strawman nihilism.
