Ok so this was suggested a bit a few pages ago but not to the extent im about to do.
Im talking introducing maps as a mean of itemizing (think outsourcing) of content introduction, as well as adding a variety to problem solving among players.
A map would be tiered (as any other), one use item that would, upon use, mark a location in the players pip boy. It would be an item of infinite possibilities, starting with easing the devs job of introducing new content (all he would have to do is "throw" a map to the mix), through giving players tons of stuff to do (from hunting for maps for profit to contracting help in solving quests) to adding a lot of spice in the wasteland with random map drops.
Imagine the dead body under the tree giving a map instead of a location, players could then sell the map on forums, stiring up the player economy and offering the way out of the grind when searching for the encounters.
Imagine looting randomest of maps from city map footlockers or magic lockers, letting you pick up an adventure instead of a piece of gear.
Imagine just plain buying of maps from trappers that would lead you to gecko breeding grounds, farmers that would sell their farms abandoned a long time ago for being over run by raiders, so on.
A problem with a certain component acquisition? Not anymore. Just ask some of the npcs for help, im sure trisha has tips on where a lot of junk might be scattered around, or where a lot of cars got stuck during the nuclear holocaust and who knows, might even yield a couple of FCCs.
Getting bored with your every day fonline? Not anymore, just pick up one of the random maps and head out.
All this with a single item.
Whoever has ever played path of exile can testify to the fact that the guys (GGG) made a wonderful job with pretty much itemizing their entire end game with a similiar (tho more complex) mechanic.
