For modern warfare, that is, anything after firearms were created, you can easily find a competent simulation for. Games like arma II that have very realistic ballistics for each of the varying weapons, to games like World of tanks where all shots done to your tanks are caculated realistically, taking into account the angle, distance and the shell and the gun that made the shot. Each tank would also have its weak and strong spots.(I'M NOT SAYING WOT IS THE MOST REALISTIC TANK GAME OUT THERE, BUT SOMETHING WITH EVEN THAT MUCH REALISM I WOULD APPRECIATE) There are games for sims planes, ships, submarines, infantry... basically anything.
However, you wouldn't be able to find a game that had truly realistic medieval combat. (There is a severe lack of non fantasy medieval games in general.) The most realistic example I can think of, is mount and blade warband. However, this game, while it has great mounted combat mechanics, still has the one giant flaw: the armor is pretty much just extra hp.
If you were engaging in medieval combat, and your opponent was wearing this:
Your first instict would not be to slash his torso with a sword. But this is pretty much how all games in that era work. What you would need to do, would be to either arm yourself with a weapon with real piercering ability, like a morningstar or a halberd, or strike into a weakspot like the neck or under the arm.
So my game idea would be like this:
1. The attacks you make would be done in a "dead island" type of targeting system, where you could precicely place your stab or swing, to hit those weakspots. It would also take into accout the direction and speed of your swing upon impact. (This would affect penetration and damage.)
2. All armor types would have a rating (this would be different in different parts of the armor), that a weapons piercering rating would have to beat, to deal damage to your health. (Go through) Swords and axes could penetrate leather and even chainmail straight on, but for plate, youd have to find a joint, or use a more specialized weapon.
3. You would have a stamina bar, which upon depleting would slow you down alot and making your attacks less effective, so those deadly strikes would be easier to execute. It would drain from striking, and getting hit by non deadly blows and generally moving around. (especially in heavier armor)
4. You would be able to pick your loadout, picking a small weapon that deals fast and percise attacks, or take a polearm to take down the slow heavily armored guys from far away. Your armor choice would be mobility vs. protection. Want to go light and very fast? Just pick leather. Want to be mobile, but have your torso protected? Wear a breastplate over your cloth. Want to be a living tank? Wear fullplate. (Just hope that the enemy doesnt out maneuver you)
While this wouldn't be absolutely realistic (still using an hp mechanic) I think it could succeed. Making hitboxes for the different locations in the armor shouldnt be any harder than doing it for the tanks and plane sims we have today.
Ofcourse, this wouldnt be hollywood style sword fighting, with you slashing around wildly, but more slow and strategic, waiting for the opening to thrust your shortsword into your opponents armpit. But I think it would be a niche deserving of a single game, it could also work as a "tourney" type arena game, or an action RPG.
