My summary barely scratches the surface; the video gets deep into the code and the ones and zeroes. I don't think there's a wasted sentence in the entire piece.

While I agree with you in general, this is actually a really well-edited video full of lots of interesting stuff about how Super Mario Bros works beyond the conclusion.

Star Wars is set in a remote galaxy where a civil war is taking place. Rebels, led by Princess Leia, are fighting against a baddy called Darth Vader and his Imperial forces. Leia steals some Imperial blueprints for a deadly weapon called the Death Star but she is then captured by Imperial forces so...

.. yes, text is great, but video can, too, be great, whether it's explaining something fictional or not. Different strokes for different folks.

So you know exactly how the minus world glitch works then? I didn't get that from the comment at all.

This is a good one. It gets right into it, and consistently provides quality information for very nearly the entire video. No fluffery, just good visuals and good explanation.

It's actually a reasonably detailed explanation that goes beyond that summary, including into how SMB levels were represented and video breakdowns of the state changes.

But TL;DR is a way of life.

The video is well edited and the animation and drawing helps explain things much better than text and some images.

But how else would we make $300k a year on YouTube?
