If you absolutely, positively, must-have all the training games available for DS, then GoNintendo guesses you'll need this game. It makes much more sense to buy this collection instead of Gamma and Beta by themselves. Still though, The reviewer feels you'll be sorely disappointed with the package. There just isn't enough to do here, even with 3 games in 1, and the price of $20. You can only go so far by improving your score, and all the activities are unlocked from the get-go. GoNintendo honestly cannot see any reasons for you to come back to this game after the initial play through. That's not to say that the game is broken, or that it's absolutely terrible… it's just not compelling. At most… you could enjoy one day with Mega Brain Boost. After that, you'll start to regret the purchase.
Look, folks: if you really want to get smart and develop your brain, shut off the idiot box, unplug the video game console, get offline, and read something. Try Shakespeare, the nonfiction works of Isaac Asimov, the great philosophers…something.
Dig up the movie Mindwalk, or even the diptych of Before Sunrise / Before Sunset – at least they'll get you thinking about the larger issues and meaning of life, maybe start you on developing an actual personal philosophical orientation and viewpoint. Don't waste your time on this crap, or such an inefficacious theorem as Makoto Shichida's apparently is.
Jeff Shirley writes for NWR:
"You have to wonder how developers keep missing the mark when it comes to these brain-type games. Do they just read the Brain Age manual and stop there? As it stands, I wouldn't recommend Mega Brain Boost."
Mega Brain Boost is a mixed bag, offering some new mini-games, but really, it's just more of the same old crap. If you really, really like Big Brain Academy and must have more of the same, then this might be for you. Otherwise, it's not exactly a must-have, especially if you already have Big Brain Academy for your DS.
