"Nintendo notoriously resisted making any of its games available on mobile platforms, a significant move for a company that's been making handheld titles for almost three decades. Then, with almost no notice, it released Super Mario Run for iOS back in December to cacophonous fanfare and promised an Android version in March. Originally planned to come out on March 23rd, the floodgates have opened a bit early: Super Mario Run is live in the Google Play store."
If anyone was looking to play it, it is out already. You can get it on your phone right now. I am actually downloading the game as a type this. I had no idea they would just spring the game out a day early.
