My son asked about a video game called Overwatch.  I don't know whether he should play because I don't know anything about it.
Overwatch" assigns players into two teams of six, with each player selecting from a roster of over 20 characters, known in-game as "heroes", each with a unique style of play, whose roles are divided into four general categories: Offense, Defense, Tank, and Support.
So it's a shoot em up game.  Do you know the rating of Overwatch? Teen, Mature, etc.
Over is rated as Teen.
Oh good.  He wanted Call of Duty and I wouldn't get it because it was M.  He's only 11.  Maybe Overwatch would be good.  
Yes becasue players work together to it can maybe help with team work skills. 
Well, since he doesn't "play well with others" it might be a good learning experience from a video game!
Yes it can maybe used as baby steps or intial steps to help him get a long with people over time!
Well, I think he will be pleased that I will allow him to buy the game based on your information!
Yes.Video games can be a very good learning tool if the right games are chosen! Hope he has fun!
