David Perry on videogames

This speech talk about the effections that video bring to us. And it talks about videogame's history, its evolution. There are many picture in the speech also some film exist, all the pictures and films can make audience know more about what speaker is talking about, because not every one knows videogame, another function of those pictures and films is to give brief intro of the following issue that speaker wants to talk. Ithink it is very well structure speech. But I think the speaker caan have more emotions in his speech. I love this speech as well as I love videogames.
