Nintendo has announced that Super Mario Run has been downloaded 40 million times in just 4 days. This is an even faster download rate than Pokémon Go and has broken App Store records. It is not clear how many of the downloads led to purchases but there was an estimate by e 3rd party of at least 14 million dollars in revenue ( and this was before 4 days on the market had passed). While it is not known how well the game will continue to do, it seems to have done its task of increasing brand awareness for Nintendo, going into the Switch era.
