I have zero nostalgia for Mario, and yet I was surprised how much I enjoyed this 30-minute video by Sheddux:

It serves as a bit of design history and even critique of early Mario games, and then in the middle it turns into an analysis of the Mario port on Game & Watch – an obsolete technology even in the 1980s, and something that could have been an easy cash grab, except someone cared.

Translating Mario’s mechanics to a much inferior tech is an interesting design challenge, plus there’s just this universal pleasure of seeing someone go extra. And the video has a nice ending message, too.
