I strongly agree with azuldemogogu's comment.
PK (Player Killing) was a very interesting attempt during the early era when Ultima Online was trying to simulate a real-world environment.
However, there is a major difference between PKs and general players.
PKs (PvPers) prepare specialized skill sets focused on PvP and are ready to ambush others, while general players mainly focus on PvM. Preparing for PvP significantly reduces their PvM efficiency, and having their hard-earned treasures stolen one-sidedly becomes a massive source of stress.
In the real world, crimes do not happen freely because law enforcement, criminal penalties, and other forms of social sanctions act as deterrents, allowing people to live their lives with a sense of safety.
In contrast, in NL’s PvP system — taking the example of Champion Spawns — everyone becomes an orange name under the customized VvV system, allowing unilateral attacks, and there are no penalties or disadvantages for the PKers.
This is not fair.
I want to enjoy the game, and I do not want to be constantly tormented by selfish PKers.
If one just wants to engage in PvP within NL system like topic starter, then the VvV system should be revised to its original form where PvP is only between consenting guilds, or alternatively, use the existing guild PvP system that is already implemented.
If open-world PvP is to be introduced as part of the ecosystem, then as Azuldemogogu suggested, PKers must face significant penalties. Since players in NL can only have two characters and the user base is small, relying solely on the player community to prepare PvP countermeasures is a difficult problem. Also, in the old era around 2000, the player community was large, and there were PK Killer organizations, but with the player base in 2025, that is a much harder reality.
Therefore, the game system itself should also include mechanisms for punishing PKers and protecting PvM players — for example, introducing "Wandering Guards" similar to Wandering Healers.
Otherwise, general players who want to enjoy PvM will only be dragged into the pleasures of PKers against their will, and the experience will not be fun.
The game will inevitably decline if griefers increase and casual PvM becomes difficult.
Furthermore, when forcing a different gameplay experience upon players who are cooperating and enjoying PvM, just because "the system allows it" does not mean "the community will accept it."
Saying "the system allows it, so you must always be prepared" after hunting down PvM players, I feel it is extremely self-centered. Such PK players should be prepared to be disliked and criticized within the community.
Personally, I enjoyed the conversation with the old-school UO style of role-playing PKs.
Some old era PKs played as bandits, demanding you drop your belongings before attacking, or communities that role-played as Orcs. However, it is not enjoyable to always have to be prepared for random griefing PKers in NL while enjoying PvM.
