I've noticed something. Logic in videogames, even in supposedly "realistic" games, is completely bizarre.
For example, in most games, a 9mm handgun is the weakest weapon, regardless of size, weight, speed, manufacturer or caliber; also, a shot to the chest or stomach would cause negligable damage. In real life, geting shot in the stomach or chest would be lethal, especially as a stomach hit would cause internal bleeding.
In game logic, all shotguns are 12-gauge, although their power could be fairly low. Also, the beginning shotgun is always a SPAS-12. In real life, a 12-gauge shotgun is extremely loud and often lethal, and requires extensive training to use. Getting hit with a 12-gauge shell would be lethal even with a bulletproof vest on, as the force applied would be equal to getting hit by a train. And of all 12-gauge shotguns, the SPAS-12 is among the most lethal.
In most GTA-style games, driving ito a light post would cause it to simply fly behind the car; hitting one in real life would caus extensive frontal damage and barely move the post.
Now, I realize that this sort of bizarro-world anti-logic is what makes games fun, but it seems like developers of realistic simulations are following the cliches because they're an established videogame norm. It's kind of annoying sometimes, especially when wielding a SPAS-12 in any FPS would make you the object of mockery for the other players.
