My son loves this.

My 12-yr-old son likes to play this, and Ive added to his homeschool curriculum. Works well. Nothing Earth-shattering, but the animations are cute and you can vary the difficulty by choosing how many continents to have it ask questions about, and you can even choose and limit the types of questions. Definitely a lot more fun than a boring geography textbook, and I dont have to argue with him to get him to play. Stack the States is very similar. Both are worth the small price.
