I think it would be cool if we could see traders moving from town to town taking a page from what they did in FO3, although maybe not exactly the same (not being able to trade with them, although that would be helpful when too loaded up with loot between towns). this would add some traffic to the roads (which besides one or three npc's, was filled only with guards or bandits) and it would be a perfect oportunity to add free form quests where you protect a caravan as u escort it to a town. (which was blaringly absent from FO3 and NV) and on the other side of the coin you could attack caravans and steal thier goods which would cause the goods in the city the caravan was headed to more expensive. which ties in with their plans of an economy in SK.
so what does the forum think, love it or hate it. I already could see how some people would think caravans would just be one more thing that makes SK more like FO3.
