There are much better 'edutainment' games out there. This game does bring education to the table, but quite frankly, it's not as much fun as others. There are two versions of the game, 'Beta' and 'Gamma' and neither one met my expectations. There's not as much interaction (this game is NOT for younger childre, not because of content being inappropriate, but because, unlike other games available, this game is just too difficult for younger children to grasp), not as many choices for play, and (sorry guys), this game tends to stay in the game case in preference to others. Save your money on this game and invest instead in 'Big Brain Academy' or 'Brain Age' if you're looking to bring fun to the process of learning for your children. My 'maturity' rating is not for adult content, this game is acceptable for any age range, as long as you are aware that younger children aren't as likely to participate due to the difficulty they will experience for the game play.
