This is the sequel to the wildly successful Brain Age, which really started a whole genre of "brain training" puzzle games on the Nintendo DS. I just got a copy last week and have been playing daily - trying to get my brain age down to a decent level (below 30) and unlocking new games.

The games are all new, but very similar in spirit to the original Brain Age games. It feels like the handwriting recognition has also improved a bit from the first version. My favorite new game has to be Word Scramble, which gives you a bunch of jumbled letters and makes you guess the correct word - it's the perfect training program for avid Scrabble players!
