Here's my take on massive multiplayer online role playing games (MMORPGs).
They consume lots of time, they suck you in an don't let you out. And especially for a 10 year old, I would highly recommend to keep him from playing one. First of all, it's really easy to get addicted to it, which could be controlled if you supervised the playing times. Even Blizzard realized that that was a problem and implemented a Parental Control a few months ago, so parents could precisely state for how long their kids could play World Of Warcraft.
I agree with Dani also. The problem is that you deal with a wide range in age group. Between 8 and 50 there is everyone represented. You can run into the danger that your son will get flamed by some overly eager know-it-all teenie who thinks it's a great idea to call the other toon names.
If I may give you a suggestion - get him a console. Get him some games that 1. don't require hours at a time to complete a goal and 2. don't have an online option. There is always time for that later in life.
Thank you, Vlad.
You identified my fears exactly.
Our computer is downstairs in a main room, so supervision would be available at all times. The thing is, I don't even want it to get to a point where I have to set a timer on the thing. I don't want him to experience the feelings of having to HAVE to be playing the game in the first place. Hindsight is always 20/20...and I am going to follow my instincts on this one.
By console, do you mean something like Playstation? He and his brother do have tons of PS games that they enjoy, as well as Gameboys and their token Tomagotchi.

Personally, I think it's plenty. Sometimes I think it's actually too much, so I set limits on those as well.
I am glad that I stood my ground. I will share your advice with him, hoping that he understands that although they can seem like fun, one can and does get sucked in.
Thanks again, Vlad!
