I love computer games when I was young. Now that I have a young little boy, I will definitely introduce computer to him when he start to understand how to use the keyboard and mouse.
Of course, there are many sites that promote learning experience and those are the sites I would like him to go to. One of them is Dizzywood, an activity oriented virtual world online game for kids age 8-12. There is no application to download. It is a web based game. I better go sign up and try the game, may be I will like it for my own entertainment.
