It sounds like the conclusion of the study continues to confirm that using your brain is the best way to keep it sharp, be it playing Nintendo DS, being engaged in a classroom environment, sudodu, or any other pencil and paper puzzle or homework. I personally don't find any suggestion that Big Brain Academy isn't more than any other method to be more effective to be particularly significant. If it keeps up with other methods, then great, it lives up to its purpose. If children are more engaged, excited, inspired and encouraged to use their brain because of Big Brain Academy, not to mention the possibly more motivating competition through the social use of the game, then the game should be praised.
I would be most interested in feedback from these 10 year old about how they felt about being a part of the group they were in, what they thought of the other groups, level of perceived group cohesion, perceived positive and negative effects of competition, and if they would be inclined to encourage their parents to get them a copy, and if so, felt like it was something to become good to impress their friends.
There is no lack of material out there to stimulate ones brain (or things out there to bring it to a screeching halt for that matter). The challenge is getting kids to take pride in training their brains and feeling like pursuit of academics endeavors would enrich their lives.
Self motivated students will always thrive in rich environments and can pick tools for themselves be it Big Brain Academy or a good old fashioned textbook. For the less motivated student that is open minded but otherwise finds 'math' or solo puzzles boring them to sleep, Big Brain Academy brings new options to parents and students. The greatest thing I love about Big Brain Academy is that it is adaptive to any skill level or age, and anyone with the skill to hold the remote is going to be able to participate.
At very least, when was the last time parents got a fun, challenging brain game that was equally enjoyable for their child?
I played this game for the first time on New Years at an all adult party, and it was a lot of fun for everybody. I don't think a wild game of sudoku in any form would have been nearly as entertaining. From someone that has had no interest in buying a console since the 8 bit Nintendo, I am strongly considering getting a Wii just for this game.
I feel this 'scientist' took a too narrow and flawed approach in assessing this game, particularly with respect to how the game could likely have been improved. Even more reason why personal feedback from participants could have had the greatest value from this study.
