Not sure about the rest of your content…but I think psychologically users are more keen to click on something they are missing out on vs something the text in the thumbnail points to isn’t something we should be spending our time with. If that makes sense.
Like why would someone want to watch a video about a game you’re declaring to be a waste of time.
That’s the sense I’m getting from the text, so I wouldn’t be inclined to click on the thumbnail.
