I am finding that by 6, our little boy has outgrown some of the types of games and activities on these cartridges - he likes Monsters University, but is getting so good on the computer, that he needs something a bit more challenging. The educational level is just right, but if they have ever played one of the Nintendo games, these start to look a little bit tame. Personally I don't like Nintendo games and prefer these - more suitable for children - but he is 6 going on 16 and his maths and English is quite good already. So for his age - to be really educational they need to grab the imagination and curiosity a bit more. These are fine for age 4 to 5 - even if the educational level is too high, but the same format for 6 to 7 isn't quite 'grown up' enough.
