Same game, more training programs.
Those who enjoy Brain age most likely do it in groups because by yourself it's rather boring. Seeing what your friends and family have made up when ask to connect the dots is fun and it's also fun to see who can get the Brain-age of 20 too. So strangely enough as is sounds the game has great multiplayer, but not in a way you'ld expect.
But even though competing for the highest score in a an odd math minigame is fun the game only has true lasting value to those who use it everyday but most people don't find this fun at all. If your willing to spend 5 minutes of your time in the day to "train your brain" you will see improvements like being able to remember 3 more digits of a train of numbers and that's pretty cool that a little game ha that power.
So if your going to give it your all everyday and you have other friends and family who like this kind of stuff Brain age 2 is a steal for only $19.99.
