The last paragraph about games seems to be mostly assumptions. Personally I would never touch a gun.
There can't be a study that could really show that, due to ethics standards. For example, you know the Millgram experiment (people told to shock someone, actor pretends to die, etc)? That was incredibly unethical, and you couldn't get funding to do anything like that. You'd need to either kill someone, or imitate killing them, trained by videogames and with actual guns, which you cannot do. Period. Would never get past the ethics committee. Notice, all the evidence cited above comes in the wake of wars. So, like most of psychology, and a lot of science, you are left with assumption. I personally believe that videogames are less effective at training than military training, for a variety of reasons, mostly about real world experience, recoil, jams, etc., but, I see no reason not to believe that the same qualities that made the one so much more efficient wouldn't be present in the other, even if to a lesser degree.
Also, why would you never touch a gun?
