What kind of video games do you like playing a lot of the time,why that type?

Is it first person shooters? What positive effects do you know for certain that these games you play have on you? Do you think first person shooters could make you able to handle yourself affirmatively if you actually were put into one of these video game scenarios in life at some future time? Or,are video games just a waste of the time you have left on earth,with no real benefits at all?
