i'd say... not that bad
This was the first nintendo ds game that i have ever played. At first it was fun challenging my brother and friends to find out who has the biggest brain but the games get boring after a little time.
The good think is that the games are pretty good for people of all ages, a good exercise for the brain. I really liked the memorise and identify section =)
I'm not telling you not to buy this game, i mean you could give it a try. It's good.
