Nintendo 2DS - games for a 6yr old boy

[Ratracerunner]

I've bought a 2DS but would appreciate suggestions of suitable games for a 6yr old. It came with Mario 2 and family want to buy some games for xmas.
Can anyone advise?
Thanks

Lego star wars
Lego batman
Mario cart

Harvest moon have some good games around - farming simulation where you grow crops, build relationships with all the town folk, look after farm animals and just generally a really fun game.

Professor Layton has a 7 age rating so may be found fun - lots of puzzles to solve to complete the story

Pokemon games have a low age rating and are good fun

Thanks for your suggestions, much appreciated
