I still remember the first time I saw my friend's kid watching someone on YouTube play video games. It wasn't a review of the game or anything like that, he was literally watching someone else play a video game. I was baffled but I accepted that I just don't get it. Today's kids were raised on different works of fiction than I was and I'm comfortable with them liking different things. Heck, sometimes I even like the new stuff.
I agree.
People have different preferences, and the yung 'uns are gonna do what they are gonna do!
And that includes watching other people play video games. Which they will do, while I will sit, silently, judging them and thinking that they are in a cauldron of wrongness, steeped in a broth of "You gotta be kidding me."
