I would like to have such a game, as well, however, your own post answers your question, as to why MOH:AA isn't a true sim. The big companies really don't think there are enough gamers out there who would buy a game like that.
They are wrong, but I truly think it is what they think.
And yes, MOH:AA could do with a better hit-location system, and reaction to such damage, but you play what you get. And, MOH is enough for me to enjoy.
I'm waiting on a VR system that I can hook up to, and have it be really, truly, like living during WW2. But, that won't happen before I die, so I have to lower my standards.
