They say sometimes less is more. In the time when personal computers were too expensive (and new) for most people, Mario Paint was probably the first introduction to a graphical art application for many of the Super Nintendo generation. I remember the first time we had Mario Paint we had difficulty getting the mouse working but once we did it was probably the most creative game I've seen until LittleBigPlanet almost 3 console generations later.

Gaming Historian recently did a video covering the history of Mario Paint. Its impact and even some of its competitors and direct (but unseen in North America) sequels.
