It's unique not not really weird - reading about music, film, and visual art is great but videos are really a very natural format for games commentary, since games are participatory in a way other art forms aren't.
Written film criticism has been around for about as long as movies have been. It simply takes skill to write well about a visual art form, and most people making videos about games likely don’t have the skill to write well about games. Or they’ve never tried.
There's people I find excellent writers otherwise whose games writing aren't so enjoyable - the issue is we all see the same movie, but have very different experiences of the same game - I also prefer travel videos to travel writing.
Anecdotally I know a lot of people who will happily watch a 3 hour video essay but if you send them a fairly average length article/blogpost they'll say TLDR.
