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.
In contrast to the in-bounds run of this game, this run skips most of the plot. There are several major collision detection bugs, including one showing that the Skip Sandwich is a fitting name for the item in ways the developers never intended. The author is able to move around the game's areas freely, completing the bare minimum number of tasks needed to keep the final battle from locking up.
