I think it is important to clarify to players that what is meant as "dangerous" here is not the typical kind of dangerous one would assume from a realistic IRL "slum" zone, where obviously flagrant displays of wealth run a risk of getting you in trouble, but there are methods and ways to defray that risk by sensible precautions. This is what I had always assumed the White City was like in my RP and how I had seen it treated by others, as well.
But that is NOT the dangerous we are talking here.
To be clear, the White City is a lot closer to an active warzone level of danger. If you enter the White City as a non-resident, you WILL be attacked, KO'd, and your PC's entire inventory taken. This is not likely an avoidable consequence unless you have access to clothing items of extremely low value, which are not currently available on grid to the best of my knowledge. Seemingly reasonable precautions such as having an empty coinpouch will not protect you, nor will wearing a hood with a cloak to cover the remainder of your EQ, as it is likely of high enough value to trigger the attacks. Most starter equipment is also likely high enough value too.
Combat will probably happen very soon after you enter the area, so the brevity of your stay is not a protection. The NPCs will spawn in sufficient numbers to ensure you are rendered unable to flee or respond in time after the first round of combat, unless you are lucky enough to get a particularly low count and you have some self-defense skill.
This didn't happen to me on several prior visits to the White City for reasons I don't know - possibly due to not being in a room with an NPC? But it is the ICly and OOCly intended level of danger for the experience, which I certainly was not aware of, and I don't think anybody else quite understood either. Understanding that it is completely unsafe to enter has some pretty significant implications for RP, probably not just for me.
I'm a big believer that for consequences to have story weight and IC value, players need to have access to the information required to realistically guess what will happen when they do a certain thing. Otherwise, consequences simply become OOC punishments for not sharing a designer's intuition about the reality of a setting/world.
ETA: To be clear, I'm not trying to start an argument about recent events. I posted because I strongly believed more specificity was needed in this post than "it's extremely dangerous, take precautions" in this situation because those words don't convey the actual IC situation, and many reasonable IC precautions do not have the coded effect you'd expect. I would also suggest the Wiki page be edited to make the actual environment of the White City clearer, and ideally there would be a coded warning when you entered. Even something as simple as an environmental echo by the entry: "Street toughs linger around the gate eyeing the people who enter for valuables; this might be a dangerous neighborhood." I have seen these kind of systems implemented well in other games to ensure people OOCly understood the IC environment they were entering.
