Super Mario Run is coming to iOS devices next week, but an always-online guarantee might mean that some fans stay away from Mario’s debut on smartphones.

Unfortunately for those looking forward to the Nintendo mascot’s debut on iOS next week, it looks like the Super Mario Run will require a consistent internet connection in order to be usable in each of the title’s three initial game modes, meaning that playing on public transport may prove difficult for fans.

In an interview that is sure to make a lot of people unhappy, Shigeru Miyamoto explained to Mashable that Super Mario Run would always require players to be connected to the internet, in order to remain functional. This is part of an effort to keep the game protected against software piracy, claims the producer. So far Super Mario Run is predicted to make over $70 million in its first month, something that Nintendo are understandably very eager to protect.
