List Command
/list is a custom command available only on the Green server (currently). It only applies to a very few, highly contested, NPCs, which drop "legacy" items which will soon be removed from the game.
/list Isn't Classic?
It may seem odd that Project 1999 on its Green server, when that server is entirely dedicated to classic (un-customized) EverQuest.
The truth is, while the command /list itself is not classic, the underlying mechanism absolutely is.
Project 1999 is Staffed by Volunteers
Classic/live EverQuest had paid GMs, who were salaried employees. Their job was to serve EverQuest players, and every server had at least one. On top of that every server many more "guides", ie. players who volunteered to do customer service work in exchange for free playtime.
By definition, P99 can't have either of those, because they're not allowed to charge players to play. Thus, all the server has is a very few, very kind, and 100% volunteer staff members. These people generously share their free time to help players who fall through the world or get in fights with each other.
/list: Unclassic Command, Classic Mechanism
Which brings us back to camps and fights over them. On live the paid GMs and guides used to resolve fights by ... yup, you guessed it: lists. We even have an archived copy of the instruction manual that Verant gave their GMs/Guides during Kunark (Kunark Era Customer Service Guidelines), and you can read about classic dispute resolution there.
