No. That’s the straw man you keep insisting on.
A simulation in no way must mirror reality.
A simulation MUST reveal ANY information about how the resolution of the simulation was reached.
Since DnD never reveals any information about how a result occurred, simply that a result did occur, it is not a simulation.
Again a simulation must reveal some information about how the result occurred or it is not a simulation of anything.
Let's see ... simulation definitions ... "must reveal..." ... nope. Not in there. You keep saying that simulations must show reasons for component pieces as if this is not just something you came up with off the top of your head and I just don't see anything that backs it up. If I am playing a war simulation video game and I shoot an enemy I don't care how my gun works, how it fires a bullet. I don't know how the simulation calculates the damage to the enemy. Most war simulations will not track body part specific hit locations, although many will do more damage if specific body parts are hit. For the most part enemies don't bleed out slowly or if they do I can ignore them once their death loop is started because ... wait for it ... I know their hit points have been reduced to zero and they're dead.
Now you could tell all those people playing those games that they aren't really playing simulation games but I suspect they might disagree with you.
