My two boys (11 & 13) love the "dangerous game" hunts on the Playstation, but there's no adrenaline rush for me when trying to blast something with a fake gun. I lost interest pretty quick, though I am a generation X'er who grew up liking the "spaceship" games. Asteroids, Galaxia, etc... As far as learning anything, I think there is no substitute for time in the field.
