Tetris is widely regarded as the game which sold the Game Boy to the world and turned it into a commercial smash hit, but for me personally, it was Mario's first DMG-01 outing which made me desire the portable system more than water, food and oxygen.
The year was 1991. I'd just moved house and was about to start at a new school, and as always there was that thorny issue of making friends. I'd moved to a new part of the town of Hinckley, Leicestershire and as a consequence knew nobody; bonds had to be formed using the traditional weapons of the pre-teen era: football (soccer to our American readers) and video games. As I had, at that point, only a passing interest in the former, it would be the latter that really broke the ice with my newfound neighbours.
Wario Land: Super Mario Land 3 was the first to feature Wario as the main lead. Take a look back at the first Wario Land for Game Boy.
Retrovolve: "The reason Wario Land has always been so alluring for me is because it essentially lets you play as an evil version of Mario."
Half-Glass Gaming: "Production of the 3DS has been discontinued as of September of 2020, but there’s definitely an argument to be made for adopting the system in 2021, especially if you just really like playing awesome video games."
