One of the biggest selling points of Super Mario Bros. 3 when it originally launched was its sheer size; compared to other platformers of the period, this was a seriously epic experience with a multitude of stages to discover - many of which required multiple playthroughs to find.
YouTuber Viktor Bohush has decided to show off the magnificence of these levels by presenting all of them at the same time in this unique video. The only concession is that levels Hands 1, Hands 2 and Hands 3 from World 8 have been "merged to better fill the grid", according to the creator.
While the combined audio track gives us a headache, the actual footage is pretty amazing - we had fun spotting our favourite levels in amongst the footage, and couldn't resist firing up the 3DS Virtual Console version immediately afterwards. Let us know what you think by posting a comment below.
