A lot of people complain that titles on anything are way too sensationalized these days, but this is the reality. A very straightforward 100% descriptive title yields almost no clicks/views, they have to be very enticing, borderline clickbaity in order to work. Clickthrough Rate on the first title/thumb combo was about 1.5%, whereas the second one had about 8%, that's a massive difference. I wish I could just write the most descriptive title and let the actual content in the video speak for itself, but if no one clicks then it doesn't matter how good the content is because no one will ever see it. And of course if I want to keep making educational content for many years in the future then the content needs to get clicks/views. So sadly I have to play the YouTube game and write titles/thumbnails that people will actually click as opposed to being 100% descriptive.

@UnityCodeMonkey Don't hate the player.
