Only 20$ fror this much addiction! It has alot, but it is lacking...

User Rating: 8.9 | Brain Age: Train Your Brain in Minutes a Day! DS
Ok so let's see... I buy a educational game for 20 bucks, I get addicted to it, I become smarter, I addicted to Sudoku, and I have fun... Now to the point... This game is about stimulating your "Prefrontal Cortex". It firsts calculates your "Brain Age", then it starts giving you puzzles and thinking games to stimulate your brain. Soon your brain age starts to decrease showing that you are improving. Now I began the game at a brain age of 80 years... Now after a week I am only 56 years old! Great Game! Get it now!

Pros and Cons
+Cheap 20$ Price
+Makes You Smarter
+Addictive
+Fun For All

-Not Many Training Games
-Not So Great Multiplayer
-Graphics are not "Ultra Super"

So yep.. For 20$ this is way worth it...
