TFin04, I'm sorry, I don't even understand your first post. Is a "fatal funnel" what the college kids are pounding beers with these days? Seriously: Are you saying that the games will cause me to stand 'frozen' in fear if bad things happen?
The fact that you don't know what the fatal funnel is shows even more that gun games are not training. They can be PRACTICE, but they are not training.
Training is having an instructor who knows more than you do on any given subject passing that knowledge down to you. Once you understand the skill sets, you can practice them. Gun games can be practice.
Gun games are better than what most shooters with concealed handguns do (nothing), but they can (and do) create just as many bad habits as they enforce good ones. Larry Vickers calls them 'training scars.'
