Platform: Wii U
Session fun rating: 8/10
My brother and his wife came over to visit and we ended up playing a lot of Wii U, including some NSMBU. While two players was really difficult, it was still possible to win. With three players, it seems like there's just so much chaos on screen that it is hard to get anywhere without getting bumped into an enemy or jumped on by a friend. We played about four levels in the first world and it was a lot of fun but I can see how people would start hating each other in more challenging portions of the game.
