EarthBound is a great RPG, designed by Shigesato Itoi in 1994-1995, and is also known by the name Mother 2.
It is best described as "random", in a good way. The game has a great emphasis on a humor, and indeed many things in the game are almost caricatured, from subplots to characters. It also has a versatile soundtrack.
Although this being a speedrun (tool-assisted at that), most of the plot of the game is intact, making this movie very entertaining to watch even as a TAS.
Unlike the previous "in bounds" movie, which aimed for a glitchless route, this TAS does incorporate some glitches while never using any that put the player out of bounds.
