The day famous youtuber Matthew Robert Patrick (AKA "Matpat", "Game Theory", "The Game Theorists") will supposedly leave YouTube indefinitely, but not without one final theory to end on.
Matpat has been making videos since August of 2009 with his first video being Blood Brothers (Scene): Swearing on the Bible. It wouldn't be until two years later where he would make a video advertising the beginning of his Magnum Opus; Game Theory (though later it would be renamed to The Game Theorists, I think). And from this spawned four more channels with those being GTLive (2015), Film Theory (2015), Food Theory (2020), and finally Style Theory (2023).
And after this day, he will simply pass the torch on to someone else who will take over on the channel.
Person 1: "Dammit, today is March 9 2024. I'm gonna miss Matpat."
Person 2: "I know. I know."
