Yeah its a role playing game and what if you wanted to role play as a father or mother?? Not that I do, just saying.
And what if I wanted to roleplay as a traveling prosttute?
Or how about as a fisherman who sails?
Or how about a Bear Trainer?
Or how about swabbing the deck on a pirate ship?
Or how about being a slave?
Or how about....
See how this becomes a problem?
"I want to be X!"
"I want to be F!"
"I want to be S!"
"I want to be Y!"
"I want to be Z!"
"I want to be C!"
Well, I think Bethesda understands we all want to be a lot of things. But they have a limited amount of time, money and resources to develop a game and they can't squeeze everything (literally) into the game.
