This time through the game I only did the critical path, no side questing at all. With my character levels this meant I got through the story really fast, which is exactly what I wanted. Although, Chapter 13 still feels slow even with super high level characters and the patch they put in to make the magic faster.
But, I think I appreciate the story more the second time. I still like the surface level stuff going on and the relationships between the main party, but this second time I understood the story better between the main protagonist and antagonist. And that story between Noctis and Ardyn is probably one of my favorite Final Fantasy stories ever. I wish it were explained better the first time through instead of having a big info dump at the end. It had a much bigger impact on me when I knew what the stakes were from the beginning.
I'm still interested to see what else they'll end up patching in and adding to FFXV over the next year, but for now I'm putting the game down again while I wait for it!
