Hello. You did not submit the article to which this question refers, which makes it difficult to answer. However, when researching the history of Super Mario Bros, we can state that the order of events is:
C. Nintendo released Mario 64, which incorporated characters who appeared three-dimensional.
B. Mario got a starring role and a new sidekick with the introduction of his fraternal twin, Luigi.
D. Mario and Luigi got a new setting that featured pipes and sewers to match their profession.
A. Nintendo launched Super Mario Bros. In the U.S., along with a new video game console.
Mario was a supporting character in another game, but he was very useful and had great market potential. This caused nintendo to develop a solo game for him, give it a name, improve the design and launch it together with the launch of the Nintendo 64, where the Mario 64 game would feature three-dimensional characters for the first time. However, this was not the only novelty. In the game, Mario as well as the protagonist, would have a twin brother, called Luigi, and both would go on an adventure between pipes and sewers to match the plumbing profession.
The game was a success, causing nintendo to launch the game and video game in the USA.
