Chris Buffa (Modojo): Nintendo has a knack for taking the simplest concepts, even ones that already exist, and transforming those ideas into key selling points. Just look at New Super Mario Bros. 2. Here's a game where the object is to collect as many gold coins as possible. This has been part of the Mario tradition since the 80s, a sub goal almost every player focused on en route to saving Princess Peach from Bowser's clutches, and yet this very idea takes center stage in the plumber's newest 2D platformer. Gimmicky? Perhaps, but some interesting wrinkles make it infinitely more enjoyable than in games past, resulting in a frantic grab for each piece of shiny loot.
