I don't think that can be modded out. It's hardcoded. The cities in Oblivion were never made seamless as far as I know.
I'm guessing Mark/Recall and similar forms of teleportation are also out, then.
A 40-minute raid to kill 5 people, one of them an old man and his wife? Osama mustn't have gone out without a bang. I wonder how many infidels he took with him.
A recent thread here motivated me to retry Arcanum in the weekend, but again I couldn't get past Black Mountain mines and uninstalled the game.
So now I'm playing some adventure games, awaiting TW2 and (lulz) Fable 3.
GRRM can beat around the bush as much as he wants, in the end it will still come down to "Chosen One reunites lands and beats back white hordes of doom". Unless he lets the Others win.
I should've stuck with Shani in my last Witcher playthrough just to spite CD Projekt with their "tasteful romance" BS. Besides, a playthrough with a butthurt sorceress at Geralt's side should be fun.
Triss is leading Geralt on anyway. I hope another miracle happens and Yennefer returns from the dead.
