It looks like Super Mario Run could potentially eat up a big chunk of your smartphone data. The upcoming online-only mobile game is said to require 75 megabytes of data per hour of “constant, involved” play after the initial download. In most cases, however, it will use a “significantly less” amount. Nintendo has yet to comment this report, but we’ll let you know whether there is any confirmation. Super Mario Run is set to launch this Thursday, December 15, for iOS devices.
