I hadn't known there were restrictions on NPCs, but it's not like I read sim rules!
So many of them are aggressive and trashy, you can feel the anger the writer had when they abandoned their former sim's drama and decided to open a new, BS-free BTB sim
As Anarch says, when a sim has the right attitude and rules governing NPCs, they can enhance roleplay. But in BTB, NPCs and their usage is fairly random, it's defined by whatever the player feels is fair
- A shitshow waiting to happen.
I think it started because men make unreliable escorts, free women wanted to travel and without escort she was collar-bait. And there were situations where a random city's slave would walk into your sim and start serving in the tavern and damn! I remember how the women in our group hated it. The freedom for females travelling willy-nilly around Gor was restricted, so NPC guards came into play.
And then it evolved to practically every woman having 5 NPC guards, with no consideration to the expense of round-the-clock security. I'd even seen peasant stall holders, and slaves, with multiple NPC guards. It's borderline powergaming and my attitude towards those players was not to engage with them at all. Here's something to consider, when you talk about cheating in Gor, the impression will be of a man dishonouring himself. But women cheat in RP and raids too. A "5 NPC guards" tag is advertising the sort of person they are.
So I'm not surprised to hear sims are clamping down on NPC ability, they were once a tool for allowing travel and were abused as a means for powergaming.
Fair NPC use is where a person includes them in every post, gives them names, involves them in events, accounts for their expense. The other side are people with the "5 NPCs" tag and will never mention them in emotes, until they're feeling threatened and just like that, this person's NPCs come into play. I've encountered 'guarded' slaves in taverns and the only time she'll post him in, is when she doesn't want to roleplay with someone in particular. It's a poor use of NPCs, a Get Out of Jail For Free card.
In other situations a person feeling threatened may wave towards a city's NPC guards and call them over. The right way of doing so, would be to roll a dice and see if the NPCs will even respond or ignore their plight.
But in saying all of that, I don't think an NPC guard should be doomed to lose all encounters, they represent the person's defence and both assailant and defender, should roll dice of equal value.
