Systems that approach this sort of simulation: TSR - Boot Hill TSR - Top Secret, 1st edition (Though there are "Luck Points" to keep it cinematic / survivable. Victory Games - James Bond RPG (but has Luck Points) Eden Studios - Conspiracy X 1st Edition - Very deadly wound system, a little complicated. (Surprisingly) Cubicle 7 - One Ring RPG. There is a stash of endurance points, but if you get run through you are wounded, two wounds kills a PC, wounded and all endurance lost kills a PC. Timeline, Ltd. - Morrow Project, very deadly, most shots will cripple or sever a limb. As I recall, the West End Games' Price of Freedom was pretty deadly. Traveller, as an SFRPG, uses points, but they are applied as wounds, so much so that you don't really want to get into combat unless you need to, because PCs die really fast unless armored. The relative balance between points and the damage that weapons do is pretty harsh. A player character can get clubbed to death, by two guys in an alley. One shot with a shotgun or laser rifle pretty much kills or incapacitates so badly that the PC needs immediate medical assistance. Overall, the system you are looking for does not really exist. If it did, all the simulationist GMs would flock to it. In the end, all that matters is the narrative. Games like LEading Edge's Phoenix Command RPG, and the Aliens RPG are the top end of simulation, as millimeter by millimeter, mechanically simulation what a weapon does as it passes through. Slightly less than that, Task Force Games' Delta Force RPG. Need real world tactics to simulate special forces raids, but it's really steeped in that actual meat and potatoes of close quarters battles and "room-clearing". Middle of the road game that tries anything like simulation, but its
very playable would be in my mind, Boot Hill, pretty much if you get
shot with a pistol and it doesn't pass through your heart, liver, or
spleen, you'll probably make it, if you don't bleed out over the next
few days, and can get a doc to sew your PC up, and infection doesn't
set in. Bottom of fast play but sloppy realism is probably Twilight:2000. Lots of real world weapons, and PCs get hurt, but they can shake it off, action movie-style. Uses points, but the relative balance is for the PCs as action heroes, easy to kill bad guys, the PCs survive what amounts to "Grazes", to keep the story going.
