EA Smarty Pants - Wii
One of the many trivia games to be released, Smarty Pants has different features from games like Scene It? from the Xbox 360. The gameplay can be altered to accommodate the age of the players, so that the playing field would be leveled so that all ages can play at the same time, but it also is a learning experience for younger players.
It also features mini-games such as a tug-of-war or dancing to determine bonus multipliers for each round. There are plenty of categories and up to 20,000 questions for virtually endless hours of play. Also you must use the Wii remote in a way to buzz in to answer the questions and also to spin a wheel to determine the next category and supports up to four-player simultaneous play.
