Hold on here...I have looked through this topic (and recieved a stack of headaches) but has anyone ever considered a few simple options for a guild to toggle at creation (and could later only be changed through a hefty price and GM action)?
RP wise they could be represented as a series of licenses that are observed and enforced by all organizations and governments.
These toggles include a full PVP status, this one would allow full out war as well as scirmishes and one on one fights between players of a guild.
To optain this licence, I think that maybe a hefty price might be required, or perhaps a special quest wherein a number of the guild members have to prove their ability through combat.
With this licence, not only are you vulnerable to PK by other priveilaged players, there would be a public roster that shows which guilds are full PK and possibly the members.
To put it simply (ignoring my suggestions about the license bit) a guild can go full PK at creation, or they can go passive.
The difference between the two can either be simple or complicated, in fact there could be many nuances added to the system.
For instance, maybe PK licenced guilds can be labeled as independants, which means that they could not be helped by guards, nor hindered. Any official ingame RP or NPC governments would likely ignore their actions and not protect members from monsters or other
"Independant" guilds.
I would love to be a passive player watching two Guilds duke it out in the middle of town and be effectively imune to their actions, and since I don't have a license my self, nor belong to a guild with one, I could not help them.
I have some other ideas on the subject, but I think they would merit their own thread....
