That's a shame, they make fun of how game companies are just enshittifying their products.
How is it a click-baity thumbnail? All of the characters in the thumbnail were in the video. I must be out of the loop on some obvious thing they are referencing with that picture.
There are thumbnail “trends” that lead to videos performing better algorithms wise and this matches it. That and the stupid face the centre guy is pulling leads me to agree with the other commenter.
Nothing necessarily specific, it's the exaggerated facial expressions and the giant contrasting text that makes me instinctively think everything in the video will similarly have the same over-the-top tone.
I know they do these images to entice children and that's whatever. I know it works, but it has the opposite effect on me. Maybe you're right, and I'd enjoy it, but my gut reaction is I'm already annoyed, and I haven't even started watching it yet!
