Good point Magnus... but for each conversation branch in F1/F2, does it average more than 4 options? If so, then by how much?
I would assume it's higher, but whether by enough is up to debate.
The number of branches aren't that important, honestly I think 4 is usually enough. What you won't see in Fallout 4 however is dialogue that goes like:
"Jules, have you seen my car? I parked it here a while ago, and now it's gone."
"Your CAR? You sure you parked it here? I ain't seen it."
"You SURE you haven't seen it, Jules?"
"Naw, brother, I ain't seen it. I'll keep an eye out for it, though. (Shrugs.) Still, Reno's a big place..."
"Jules, I have this crazy HUNCH you know where my car went. If you don't tell me where it is, I'll use you for target practice. Now talk."
"Brother, I don't know NOTHING about your car. I AIN'T seen what happened to it, and I DON'T know where it is. (He throws a hateful glance at Cody across the street.)"
"Really? That sounds like a load of SHIT to me."
"All right, brother, all right! ...I seen some guys take the car not long ago. But there were too many of them for me to stop, y'know, and --"
"Shut up and take me where they went. Now."
"Okay, okay..."
"By the way... Jules? If you so much as GLANCE the wrong way at that kid across the street, I'll come back and kill you so many times you'll need multiple wills. Understand? Now lead on."
