Roleplay in the Wasteland
... can't be the fully roleplay - why? Because of its gameplay style and priorites of plaers, and standing near barrel in NCR isn't that quite roleplay, and you cannot do it normally, because other players might don't want to do it, so they just kill you for teh lulz, instead you can try in closed groups in some secret place but it gets fast boring, its like bugged forever feature.
But if any pvp faction is interested into it, it may work, but it will end sadly (WWP, TSAR in Redding, RDA in den).
