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.
