@1: As a courier of the wasteland you must travel enormous distances, and on the way you will face people who will attack you. Are you saying you've never been shot in the head during your time place New Vegas?
@2: No, I am saying, you live 20+ years, and have been doing the courier job for a while now. It's only natural that you'd have been shot in the head more than once.
I'm not arguing that it was stupid to include just 2 head shots, I am asking for a user's view point on how the Courier in all the years he's been in the courier business, lived his life just being shot once. It's normally expected for them to get shot multiple times. To me, this one head shot in the span of many years of travelling makes me think he was either magically protected, or it's a funny funk in the story.
You're confusing gameplay mechanics with gameworld 'reality'. As a *player*, you'll likely take shots to the head dozens, or even hundreds of times through the course of the game- but since you are the player, they can't have little things like mulitple brain-splattering headshots keep you down, so you always get back up again and keep on going like the Vegas Energizer Bunny. But before you magically took over control of this Courier character, and turned into the cat with 999,999 lives, you weren't having all this gratuitous slaughter happening every 5 minutes throughout your 20+ years. In the 'gameworld reality', people die, for good, when they get popped in the head. Your survival of those two slugs from Benny, is the truly miraculous and unusual thing- but it makes for a good plot starter, even if it's rather unlikely you really would have survived them.
So anyway, sure, while you are in control, it's a shootout every day, every hour, every other minute, if you choose to make it so- gotta keep the player entertained. But that's not the constant gameworld reality for the rest of the npc chars in the game- if it was, they'd all be dead, and the wastelands truly would be empty. And it wasn't the reality for your Courier either, until Mr. Player takes over. Did everybody in Goodsprings have old bullet wounds in their heads? Did every 20-50 year old NCR soldier you run into have lumps on their skulls from missing chunks? Was every prospector and trader and merc you ran across a survivor of multiple head wounds? Of course not. When you shoot any of them in the head, they die. Permanently.
Gotta learn to separate the more-or-less sensible gameworld reality that all the NPC's live in, versus the fantastically unlikely reality the player gets to experience.
