"Which is why I wonder if gun games really teach survival skills or simply game playing skills. I suspect it is the latter. "
This issue, like most issues, is not simply black and white. All the shooting games I have been involved with are games, there is no doubt about that. But at the same time, by participating, you become much better skilled with your weapon and the manual dexterity that it takes to be skilled with your chosen weapon. Maybe as a shooter concerned with self defense you practice drawing from a holster, drawing from concealment, shooting for accuracy against a clock, engaging multiple targets from ranges close to contact distance out to maybe 50 yards, shooting with flash sight pictures, point shooting, shooting around baracaides, shooting from various positions (sitting in a chair, sitting in a car, lying on a simulated roof, shooting prone under obstructions, shooting strong hand, shooting weak hand.........) rapid magazine changes, deciding when the optimum time is to make a magazine change etc. After all, you won't learn these skills unless your practice them. So why is it that if you take these drills and incororate them into a shooting game that it becomes something to be negative about ? What is wrong with trying to become the best you can be with your carry gun ? What is wrong if in so doing you keep score and compare how well you did this week with how well you did last week or how well you did compared to your friends ? If you don't keep score, if you don't time yourself, you have nothing with which to judge the results. Trap shooting isn't bird hunting, but it teaches you some of the skills needed to hunt birds. Silhouette shooting isn't big game hunting, but I know two years ago when I had to take an off hand shot at a mulie, my silhouette shooting played a significant role in my making the shot. As One said, "Train as you fight, fight as you train." There is no way we can realistically simulate combat with our chosen weapon. So, we have to do the best we can. If all you do is stand 7 yards from a target, fire a string, stop and reload from a convienient box of ammo lying on the table, you arn't doing much training for anything but standing 7 yards from a target................. Having a little pressure on you when you shoot is a healthy thing. When you are plinking and you miss a shot, you simply fire another one. But, when you are keeping score, every shot counts. Shooting in front of other people, shooting against the clock, having your score posted, really being concerned with how well you are shooting doesn't provide the raw terror experienced in a true life or death situation, but I am convinced that it is better training than shooting beer cans at the dump. Being able to evaluate your guns reliability, how fast you can pick up your sights, how well your holster functions, how your dress effects your draw and magazine changes under pressure, with no alibis, to me is a valuable tool.
How much of a game it is is kind of up to you. You can choose to participate using your bone stock carry gun with your carry holster and your carry ammo, wearing the clothes your would normally wear on the street. Or you can choose to play the game and shoot a custom race gun. That is up to you. I have shot matches where off duty police officers wore there duty belt complete with PR24 etc. They tried to shoot each senario as tatically sound as they could. They saw it as another training exercise. If the rules allow you to reload standing in the open, that doesn't mean you have to. As long as your don't violate any safety rules you can usually choose how you want to handle the senario (within reason).
