I don't think that Video Games are harmful. They are there for entertainment, and actually, I think that in some cases they prove to be better for you than, say, sitting down and watching T.V. for hours on end, depending on the video game. Games such as World of Warcraft make you make decisions, sometimes there is a lot of math involved for you to make those decisions, there are countless formulas that in order to get, you one, have to be able to find the formula in the games files itself, or two, find it on the internet. I know that playing video games has helped me with my motor control as well. I used to be able to type about thirty words a minute. Now I can type upwards of 80. Thought, and speed.
My mother thinks video games are taking my life away. That because of these video games I have no social life(so little does she know). She is sooooooo biased though, and has a selective memory, soooo... yeah.
Video games can harm though, people have died from lack of sleep because of them. Usually I think this is the persons fault, not the video games. You have to know when to quit(after long periods of time playing them) or when you have to do other things such as eat, go to the bathroom, go to work, etc.
