So I have New Super Mario Brothers U, the stand alone version and I have the combo pack, the Mario Brothers U and the Luigi U. The stand alone version is roughly taking up 2 gb on my hard drive, the combo pack is taking up about 17 gb! I have not played through the whole game but why is there such a big difference in space needed? I want to delete one so I can install a different game but what should I do? Looking for suggestions.
