I find most of the "original" content these days on YouTube to be boring—all I do on the platform is watch gameplay videos, an unboxing or two, and the occasional cringe compilation and listen to music. Sure, I could comb the website for the "good stuff", but I'd rather employ that time into something else.
That "10-year hunt for the lost McDonald's DS game" video you mentioned was a good one, though, which surprisingly was recommended to me by YouTube.
