I'm thinking of Rolemaster.Can you write out an example or two to illustrate what you mean? I’m interested specifically in how the attempt at organic mechanics fails.
As one example: the resolution mechanics generate a lot of detailed injury, which then interface with the healing rules. Both natural healing and magical healing have detailed rules. Natural healing depends on the nature and severity of the injury. There are also rules for determining whether an injury brings ongoing nerve damage with it. Magical healing is spread over five main spell lists (Concussion Healing for bruises, burns, frost bite, and concussion hit point loss; Blood Healing for ongoing bleeding; Bone Healing for injuries to bones and cartilage; Muscle Healing for damage to muscles and tendons; Nerve and Organ Healing for nerve damage and injured organs - and each spell list has many spells on it).
The effect of all this is to have a very clear sense of how a person has been hurt, and how they are recovering. In this way, the "simulationist" goal is served.
But it is not very interesting. It is extremely technical, requires careful application of the relevant rules, and also tracking of the passage of time. And whereas systems like Burning Wheel and Torchbearer have somewhat systematic ways for handling the passage of time (eg Lifestyle tests, training), Rolemaster does not - the GM has to manage the passage of time with the same resources that the game provides for handling random encounters in an "adventuring" context.
In stark contrast to this sort of approach to injury and recovery is Prince Valiant, which has, as its core recovery rule, the GM decides how long it takes. And which has no elements (like healing or recovery of spell points) that makes the tracking of time matter as anything other than colour.
There is nothing less realistic, as far as fighting and injury are concerned, about the fiction we create in Prince Valiant than the fiction we create in Rolemaster - eg, when a PC knight was run through the shoulder by a skeleton lord's magic two-handed sword, his recovery took a long time. And it doesn't create long periods of uninteresting calculation and technical reasoning at the table. But it is all done by GM stipulation, not "organically/emergently".
Does that give you a sense of what I have in mind?
