Lets see Big Brain Academy for the Wii is a good game, but I found it much more fun when you played with another person. The games has everything from watching birds and then trying to find them again to wack a mole with the right symbol on it. All of these are supposed to work your brain. Playing all the different mini games is kinda fun but it get old fast if your playing them by yourself. I would say that this is more of a rental then anything else.
My whole family really liked this game, but I dont think I would purchase it. I agree with the other reviews about it not worth buying. We had fun for a few days, but everyone seemed to go back to Super Mario Party 8 pretty quick.
