Query: 20-Questions Handheld Game - Big Disappointment

This game, although somewhat fun, is very limited in its capacity. The only way that the game is able to guess the item about which you are thinking, is if you choose something (an object, etc.) that is very simple, and that you can describe with great accuracy. Otherwise, the game guesses your thoughts incorrectly most of the time. It is not very sophisticated, and is truly not worth the money. In other words, do not buy this product.
