Valkyria Chronicles. Essentially, I was playing at midnight, decided to finish one or two more missions after clearing Ghirlandio (Selvaria, it's not nice to carry and operate a crew-served gatling one-handed, especially when we have to start in a killing ground), then looked up to see it was 5 AM and I had finished the game.
Best theory I ever heard about the ending of FF7 was that since Holy Materia is designed to purge the planet of taints and corruption that would otherwise endanger it, it wiped out all humans, as well as Meteor, for the destruction they wrought on the Lifestream via Mako refining. That's why the only main character you see is Red XIII, and the reason Midgar was abandoned. Pity they then came out with their sequels.![]()
