Here is the plot for New Super Mario Bros. 2 from the official website for the game:
“Trouble always seems to find its way to the Mushroom Kingdom! Just as Mario and Luigi go off on a coin hunt in the sky, their beloved Princess Peach™ is kidnapped by the dastardly Koopalings. The brothers have to venture through over 80 stages to rescue her, grabbing an endless deluge of coins across land, water, air, and snow along the way.”
Same old, same old. Peach gets kidnapped once again and Mario and Luigi go out to save her. Can we get something a little different Nintendo? Plus, there will be over 80 levels in the game. Does that mean there will be 8 worlds with 10 levels in each plus whatever extra worlds they add in?
