Shorter Nights
This is a really small change, but it’s one that has pretty significant impact on how you play the game. After beating the game, Final Fantasy XV recognizes that Noctis and his crew have successfully restored light to the land of Eos. This means that nights will now be a lot shorter, and you’ll have even more hours in the daytime to mess around with. Prior to beating the game, nights would start at around 6pm and end at 8am. However, after beating the story, you’ll get about four more extra hours of daylight, allowing you to complete even more daytime quests and hunts before time runs out.
Not only that, Ignis will now be able to drive the Regalia at night, meaning players no longer have to manually drive around the world once night falls. Both of these are incredibly useful changes, and should help with faster completion of side quests and content.
