As Nintendo's first Mario game specially developed for iOS platform (rather than just a parkour edition of SMB, developed using the free Unity game engine), Super Mario Run also became the second annual topic of mobile game after Pokémon Go. In a sense, Super Mario Run is a bit similar to Square Enix's famous but abandoned "GO" series of mobile games. They both, in the premise of keeping the original game art style and basic settings, were specially optimized for mobile devices, and simplified the game operation, in order to attract more new junior players.
