Everyone that's played Super Mario Run, Nintendo's first proper foray into the heady world of cross-platform mobile gaming, has had a lot of good things to say about the experience. It's unfortunate then that the company appears to have put a bit of damper on the occasion by requiring that you have an always-on internet connection to play the supposedly-on-the-go game.
Nintendo's design supremo Shigeru Miyamoto explained the requirement in a conversation with Mashable. In summary, that reason for it is 'piracy', with Miyamoto elaborating that, "We view our software as being a very important asset for us [...] Unlike our dedicated game devices, the game is not releasing in a limited number of countries. We're launching in 150 countries and each of those countries has different network environments and things like that. So it was important for us to be able to have it secure for all users."
Piracy prevention is at least an understandable justification for Super Mario Run's forced internet requirements, but it does rather ignore the practical ramifications of the decision. Unless you're permanently tethered to wi-fi, the chances of you having continuous access to the internet, and thus being able to play Super Mario Run, as you roam the UK are abysmally low thanks to the country's erratic mobile data coverage. You can pretty much rule out train, tube, plane and car play then, rather defeating the point of a mobile game.
