Yknow its weird, I haven't watched Game Theory properly in years- but seeing Mat step down kinda still hits me like I had been, he really is just that weird uncle of YouTube that everyone knows and (for the most part) likes.
He made an impact on internet culture that was so massive that I feel like we dont even really consciously recognize it anymore, hell I dont think anyone can hear the word "theory" online anymore without finishing the quote, or at least thinking about it in the back of your head.
Either way, happy he realized what was best, even if what he does is faaaar past my demographic by this point, I respect what he did for a younger me, and the ultimately really positive influence he had as a creator, cause when your biggest controversy is getting Toby Fox to yell at you a bit, and resolving it like a day later, Id say thats how you know you have a pretty clean record, lol.
But hey--
