Mega Man has been in several series and this is the first game in what is called the Mega Man Classic series. This first game established many of the conventions that would define several Mega Man series. Most notably, Mega Man established the setup of a number of stages, each with a Robot Master at the end that, when defeated, would pass on its unique power to Mega Man. Mega Man is made up of six stages, with a Robot Master at the end guarding a weapon. The stage select screen allows the player to choose from these six stages, and when they are all completed, the seventh and last stage appears in middle of the menu, replacing the text "Stage Select, Press Start". This last stage is in fact more like four regular stages linked together, some a bit shorter than average, but with very hard bosses.
