I'm still excited for and still getting the game, but it's definitely not surreal to me; after you've waited 10 years for something you get numb to it: same thing happened to me with Ridley and K. Rool in Smash. Even worse, Let's Go Pikachu/Eevee should've been N64 games. I feel like we are living in a gaming generation of making up for lost time... Mario Odyssey should've came out 10 years ago.
I'm seriously considering taking a personal day the day it releases and just playing all day long. (I'm a school teacher so I don't have a lot of these if it's not June, July or August.)
Holy diddly if I was a student and my teacher was taking off to play KH3.
Starting with January 1st, I'm going to do a story only run through of all the KH games, including Days and Coded. I'm going to time it so I'll be done with 0.2 just before midnight the day KH3 releases. Provided KH3 releases at midnight of course. I'm actually a little worried there won't be enough time to finish a run of the series.
I would start that now and take your time, and I would leave whatever time you have left after completing 0.2 as a break to keep things fresh and build hype.
A little off-topic, but it is kind of insane how my gaming experience is plotted out in route to KH3, and it is almost a perfect buildup from least to greatest:
September - Spider-Man
October - Mario Party
November - Pokemon Let's Go
December - Smash Ultimate
January - ...
Well Spider-Man is definitely not least, but it's good to start with something like that that can keep you occupied. I know you guys don't give a diddly, but NBA 2K19 is gonna be a consistent time sink for me throughout as well. Tunic is also a go.
