N+ is fucking hard
Seriously. It’s very hard. Call of Duty 4 on Veteran? You have AI friends to help you through the hard parts. You have a GUN. In N+? Your only weapon is a self-sacrificing friend in co-op to blow themselves up on some mines. That, and you can jump. Not ON to anything, mind you, ala Mario. Touching them will kill you. But you can jump over them at least. Unless they home in on your position / lock-on and track you.
Still, it has been getting great reviews for its 4 player co-op-ability. And in this regards, the game is excellent. The game has a stick (go left and right), and a button (jump). You can give the controller to anybody and they will understand what to do. More so than Mario Party, Halo, Raving Rabbids, Rock Band, or any of those other Party Games. The games difficulty may turn some people off, but as long as it is not taken too seriously it is hilarious to watch failure as rag doll parts clear an entire mine field for the rest of your team.
