The problem is we are all more experienced gamers, and we expect to resource manage, and because of that we end up encumbered with ammo and weapons we are saving for that special moment... we also take the time to go out of our way early on to stock up on free ammo for later in the game...
I once watched my cousin play Skyrim... He usually plays CoD, Battlefield and Fifa and the like, and to be hones I was surprised to see him with the game... He was near the start, and was playing through the cave where you find the first shout, the one where you retreive the golden claw for the shop owners. Not used to the mechanics, or the way the game works he spent a lot of time just running round finding enemies to beat up... that was pretty much it... he didn't use stealth, he didn't use a bow... hell I let him get to level 6 before I pointed out how to increase his skills on the level up! He looked around for weapons or armour, but only took the biggest and best stuff, but would ignore valuable trinkets if he found them, as he saw no need for them...
Of course, everyones gameplay is different, and the way he plays is not wrong, or anything, but it left me wondering what he would do if he found a part that he got stuck at... a hard boss or something. He would probably just bugger off somewhere else, and come back with a bigger sword later on I expect, where as most of us would stop and look for an alternative solution... I also don't imagine he will ever try alchemy, or summon any allies, or bother finding ammo so that he can use a bow... tha just doesn't interest him. I also thought that if it came to trying to gather money for a house or something that he probably wouldn't bother with that either...
What I am trying to say is that for the game to be accessible to everyone they have to make it so that people not used to it, or with different styles can play too... Say for instance that somehow my cousin loses his sword (I once pressed the wrong buttons in the menu on oblivion, on a steep slope and dropped a dagger, it fell down the hill and landed in some grass... I never found it again during my massive search...) and had to rely on a bow later in the game. The game will still provide many arrows so that he, and people like him, can still play, even if they fire many arrows and hit nothing (as I expect he would, he plays in 3rd person, and sometimes seemed to struggle to hit enemies with a sword with his erratic 'Halo style' close combat!)
Well... that's one reason it could be anyway!
