Query: great educational game system!

We purchased this as a Christmas gift for our almost three year old - and he was very excited!! Along with it, we purchased the Bob the Builder and Thomas cartridges. It was very easy set up - I would strongly recommend purchasing the adapter to save yourself from continuing to purchase size C Batteries. Although each cartridge offers only three to four games, there are different levels and it is amazing how much keyboarding and basic screen navigation he's learned already. The games all reinforce letter and number recognition, colors, shapes, following directions. He plays these games frequently - recently we also purchased the Finding Nemo and Go Diego games.
