Going NUCLEAR on my Backlog

So... I have 800+ games on my backlog? Help! #backloggaming #gaming
The start of a journey, it will extend for many months, and I want to leave a record behind of the task, time, effort, and my thoughts behind playing this many games.
Hopefully by next year around this same time I've completed everything from the list.
Most of the footage is my own gameplay, if it isn't I've credited the proper YT channel. I have those games, finished them actually, but I didn't have the time to record them all.
Also, if you are a google sheets pro, I take tips and tricks!
