Adding on to what I said in my last post, there's a lot of military families, and people with friends, spouses, siblings, cousins, aunts, uncles, and grandparents who were in some military in some sort; more than you know. I'm sure such a game could peak the interest of those people, especially if they are gamers.
This brings Abraham Lincoln's Secratary of State, William H. Seward into mind. He got stabbed several times in several places that would seem fatal, and yet he survived.
I know it was a stabbing rather than gunshots, but it just reminded me of his hard to believe survival.
Yeah, I think the "dying" process could be something brutal, real, and yet beautiful (or brutally beautiful or beautifully brutal) that games under use. Some of the most beautiful moments in gaming is when a character dies, including in combat. In the Metal Gear franchise, many bosses you kill leave you feeling kinda sad, and some even really evoke emotion. I think such a negative yet positive thing is pretty beautiful, and it makes games better.
I bet if games like Call of Duty showed your character dying after getting shot slowly and in a sad, depressing, and painful fashion, quite a number of players would actively try to die a lot less often, and thus play it safe rather than just running through the middle of a battlefield like you got nothing to lose.
