For me Fallout dident feal like a real world and to many small obstacles where impossible to cross event thow u could spend 10 min on walking to the other side of it. i felt like a little baby that only could crawl in the land of the adults :) If the terrain looks like i could walk there i should be able to do just that, i dont expect to be able to climb mountains but i do expect to go/walk where i can in real life.(exept the borders of skyrim of course.). When they said the rebuild the engine i sure hope its from the oblivion engine and not som kind evulution based of fallout engine. True... Still Oblivion did still have that problem, though it was worse in Morrowind. It seemed like any rock, no matter how flat, was impassable if this is just a block setting, do u think its possible to change it in the ini files or with a "mod" or u think that would break the game compleatly?
