I like Wii Party U, there are so many different types of game modes and games within games. That drawing minigame is pretty fun with a group of people, there's like a tetris-ish puzzle game just hidden away in one of the menus, there's a mini game where you play like reverse hide and seek with the person on the game pad giving you directions to find them, the fashion board game has a decent amount of strategy to it, there's this game buried in a menu that's like a cross between Go, Connect 4 and Wario Ware, and oh man there's Spot The Sneak where one player is given the ability to cheat in mini games but at the end players vote on who the cheat is so if people catch onto your cheating you get a penalty, if players indict an innocent they get a penalty. That's like 5% of the game types in the game.
Some of the stuff in Wii Party U is terrible, one of the minigames is literally a random number generator ostrich where you have a 1/4 chance of winning, but there's sooooo much stuff in it I find it hard to believe there isn't atleast one game mode you'd find appealing.
