I found this funny moment between Prompto and Noctis during one of the camping cutscene.

I have to say I really like the way the characters interact with each other. As long as there's a lot of entertaining and unique dialogue between them throughout the game, I don't even care if the story sucks. Fun characters can save even the most cliched and boring story.
Despite me saying it before, I wasn't actually sure if this was a day one purchase for me, but this thread has slowly made me more and more excited.
