My parents got us a Wii and our 4 year old is very excited about it. I am looking for some game recommendations for games that he can play on his own once I set it up for him.
at four my wee girl used to like playing wii sports resort, (well some of the events)
and my nephew loves my "go vacation" he is about the age of your boy. on go vacation he can drive around to his hearts content, playing games as and when he feels like it. my girl loves it too.
think sports resort where you can explore the island freely, cept 50+ activities and about 12 different forms of fully controlable transport, not to mention the old walking and swimming.
