Ok, I have been keeping track of this thread, but I haven't read everyone's posts thoroughly, and generally when people start getting nasty, I lose interest. So if I just repeat what others have said, please accept my apologies ahead of time, and I will be re-emphasizing something I have already posted.
It seems to me that there is a fundamentally flawed assumption at the base of all this discussion about pk'ing. It appears to me that people in this thread actually think that a classic shard, or shards, are going to replace, and/or do away with the game that is played on the regular production shards. This is not going to happen folks.
It seems to me that you all are trying to think of ways to protect the "sheep" that are going to flock to the classic shard. In my opinion, this is not going to happen. A classic shard is going to be frequented primarily by people who have good memories of the "old days" in UO, and some of the curious, or those that get talked in to checking it out by friends.
The sheep that played UO in the old days, those tens of thousands of victims who gladly flocked to Trammel when it opened, are never going to make a classic shard their home, and for the most part they don't even exist anymore. You don't need to worry about trying to protect them, because they aren't going to make an appearance. You need to worry more about keeping your classic shard true to the era that so many have fond memories of.
If you start messing around with pvp switches, excessive penalties for pk'ing, and/or specialized pvp zones, you are going to destroy the very thing that will attract your target audience. Let me repeat myself. You don't need to worry about protecting the sheep, because there aren't going to be any sheep on a "classic" shard, any more than there are sheep on Siege Perilous.
There are so many options for the sheep out there that simply weren't there in the early years of UO's life. And I expect most of them are far more attractive to sheep than a "classic" era UO shard. All kinds of MMO's with pvp switches, dedicated arenas for pvp, servers with pvp rule sets, and servers without them.
I was a communications major in university, and one of the things that gets drummed into you in communications studies is that you need to understand your target audience. That is something that all of you advocating for a classic shard need to take to heart. Your target audience isn't the sheep.
Your target audience is people who have good memories of the pre-Trammel days in UO, their friends and a few that will have their curiosity piqued by what they have read of the old days in UO. Unlike the old days in UO most of these people are people who have likely been playing MMO's for at least ten years. These people are gamers that love pvp, or at the very least a world built around pvp, and who are far more sophisticated when it comes to their knowlege of computers, and MMO's than we all were back in those days. And they all have strong opinions.
These are likely people who were power gamers back in those days, but who now have a decade of experience to add on top of that. They all have computers and connections that are much more powerful and faster than what was available back then. These are not sheep, and they don't need to be protected from the big bad pk wolves.
