I love the lighting, it's seriously great. That shot with Noctis and Prompto in the gas station is so atmospheric. I hope that the weather system is as dynamic as they've said, because I love me some rainy and cloudy environments. It might sound silly, but it really adds to the game and makes me want to play it more (the same goes with the day/night cycle).
I'm glad that hunts are back, hopefully à la FF XII; I really liked those in that game. Especially the Bestiary, it really made the game's lore deeper. And let's hope they don't implement your typical MMO sidequests. I liked Dragon Age Inquisition (despite not being an amazing game by any means), but man, that sidequest design has to die/diminish.
Also, for a moment, that final scan looked as if we were controlling Prompto.
Hold me ;_;
