This game is certainly original in many aspects. The only game I can think of that it is remotely similar to would be 'The Lost Mind of Dr.Brain" which was a PC game in the late 90's. The brain age evaluation is interesting, but sometimes does not seem to make too much sense. While playing the same three games, I have performed better only to score worse with my overall "BrainAge". How does this work? Does it not want you to maintain a low brain age? The other small bit I have to pick with this game is that you cannot attempt to re-test your brain age twice in one day. Between "Big Brain" and this game, I would likely go with game if you are past your teens, and find just the pure mental challenges interesting. If you need bells and whistles, there is no question that you should consider "Big Brain: instead.
