I believe Fifa 18 will sell around 13-14 Million units (PS4), if its less it would be disappointing.
I have no idea how Super Mario Games sold before, its gonna be HUGE, but will it be something like 14-15 Million!?!? I dont know, but obviously Super Mario will sell for years just like Zelda and Mario Kart and Fifa 18 will sell for 1 year.
I would say Fifa 18 will win, even tho when Fifa 19 comes out 1 year later, but lets see how it goes.
