But for New Super Mario Bros. 2 for the Nintendo 3DS, Nintendo has stuck with a familiar formula, though there’s been a slight change in one of its components. Yes, of course, Mario and Luigi are still working together to rescue Princess Peach, who, as expected, gets kidnapped by Koopalings. But that slight change to the formula? This time around, it’s all about collecting coins."
