Another good one is Madagascar....and I would heartily recommend monkey ball.....especially as it has racing games, air hockey, golf and paintball games.
I like the brain training but think that a seven year old might find it a bit like doing schoolwork......especially the mental arithmetic.
If he likes problem solving, then Contact might hold his interest too.
It is a shame you can't try before you buy.
I like all the ones mentioned....so I guess I have the mental age of about 7.
