So I stumbled upon what is allegedly an excerpt from the intro to Fallout 4's script on Kotaku, and I'm not sure what to think.

Assuming this is accurate, I dont know about this. They've decided my back story, family's back story, character's attitude towards the world, and my characters attitude towards his family. This is even before getting into the whole voice and compressed dialogue option thing.
Then compare this to New Vegas, which says "You're a courier. What that actually means in this world is a bit up in the air. You have a chip. Fill in the rest yourself. Go."
So, what do you think? Is RP going to be limited, and if so, how much of a hindrance will it be to your engagement in Fallout 4?
