I am forever saying that its difficult to get quality help, but here is my honored to see this post. And also, I found the related website:http://www.kidsplay123.com/learning-games/ about learning games for kids.
I've come up through the ranks. Atari Pong (40 years old on 9/20), Atari 2600, Commodore 64, Ninetendo, Gameboy, Ninetendo 64, PC, Sony PS 2, and of course Ninetendo Wii.
Mine was the super nintendo. It was my brothers, I wasnt even born when that thing came out. It was such a beast, I used to watch my brother and sister try to play zombies ate my neighbor and they never really got very far.
Commodore 64 i beleive. A beautiful machine which i hated so much. Thought it was awesome until i moved swiftly into the other consoles of the time and realised it was awful.
