well you see someone in town shouting buying mentats, you come to him barter for the price, then you bring mentats, then you both go to world map, then you trade, whats no alive? Arent players trading between each other? Sorry bro, but your suggestion would just give devs more work without giving any new continent or possibilities.
That kinda unhealthy habit.
95% this guy does not have any mentats with him. Or otherwise, he will be stealed, bursted, shitted on head and called noob.
When you decided finally to trade, you go to bank for money or to tent for plasma pistol or whatever, he goes to tent for ments, then you go together to worldmap. Does it looks have any sense role-play wise? No. And by the way, you can be bursted anyway in process.
Once I made 800000 deal this way. I 95% was sure I'll be killed in process. (Hi, Michaelh139
) and was really amazed that all came o'k
Imagine several crafter, with stuff - they trade easily (they paid for that, remember?), giving radio advertisements (come to BarterGround, best Drugs from Doctor Eex!)
You take caps or your stuff and come to market, trading, choosing from whom to buy and so on... Impossible in NCR or even VC
This idea allows to have good quantity of players, REAL BAZZAR, not that grieving fest in NCR.
And this location can have a guarded parking for caravans and so on and so on.
And btw, A NEW location is NEW CONTENT and POSSIBILITY, is not it?
