Guys, please stop using the argument about the OORP trade routes going in there.
I will put it in solid ice. THEY ARE GETTING NERF. Traders won't have any businesses there anymore.
Whilst the idea is interesting, there is too much complications and I guess it couldn't get implemented correctly.
EDIT: A key MIGHT work. But what about as i said, new Characters? What about order based Characters? What about nomads? What about characters with special RP?
Unless you make the commodity sold in some key(restricted) locations, and for those with weird RP, make some kind of scanner that would be mounted by player with the ability to jump with the gate.
