WarioWare Inc - Mega Microgames! (or stylized as WarioWare Inc.: Mega Microgames!) is a series of minigames developed by Nintendo R&D1 and published by the company for the Game Boy Advance. The series is considered one of Nintendo's greatest success stories, and has been a fan favorite for years. In PAL regions, it is referred to as WarioWare Inc.: Minigame Mania.
Minigame Mania was released as a free-to-play download for the Game Boy Advance in Europe on March 21, 2003. The game's storyline revolves around the company's founder's attempt to start a new business and succeed. The game is unique in that players are presented with challenges every few seconds and must solve them to progress. The game requires fantastic reflexes and complete attention to complete the challenges.
The game's minigames have an anthropomorphic animal character called Wario, who is a humanoid mascot. The games are made up of a series of challenges, and each task lasts three to five seconds. The tasks aren't mind-bending, but they are entertaining. WarioWare Inc - Minigame Mania is a great example of how Nintendo can take an otherwise simple idea and turn it into AAA quality gaming.
