So. We're doing the first test of the website (The JohnByNightEngine as I call it), and a few issues came up around tracing.
Multiple traces: how should we resolve multiple observations of the same individual? Let's say Nefersedjem watches for both gauging and growth in the Streets, and Marcellus happens to do both. Nefersedjem gets two "notices" that he observed people, right? But now Nefersedjem traces one of them on the next turn. Should he learn the that both are the same person? I'm inclined to say no, and if Nefersedjem traced both of them he's learn both are Marcellus.
Now here's another item: Nefersedjem is watching for gauging again in the Streets when Tanit-Ishtar is gauging the streets, but Tanit-Ishtar is doing it with a level 0 action (i.e. just augments alone from, say, Investigation). Now, it seems clear that Nefersedjem should have a chance to gain information, and I've written before about giving level 0 and 1 actions a die or two of free concealment and the like. But let's say Nefersedjem is successful at noticing and then tracing this level 0 influence: what next?
It doesn't really make sense for Nefersedjem to have a trace on Tanit-Ishtar because Tanit-Ishtar doesn't have any influence to trace. So Nefersedjem just learns that it was a level 0 action and that's it? Or Nefersedjem learns it was a level 0 action done by Tanit-Ishtar? It might be really frustrating for people who attempt to trace level 0 actions and simply keep coming up empty handed with no information, but at least learning it was someone acting alone might help.
It makes sense that you can't actually get a permanent trace on an adversary with a level 0 influence because there's nothing to trace and they'd essentially also automatically be able to refresh (by the rules, refreshing a level 0 influence would take 0 points). Maybe instead of levels of Conceal, level 0 influences should have a die of something else, so that there's about a 50% chance that Nefersedjem just learns it is a level 0 action versus learning it was a level 0 action done by Tanit-Ishtar? This is a much more complex and unpredictable thing...
Another solution is to bring the human brain back into things. The system could flag every successful trace of a level 0 action and the ST might embellish the mechanical result by giving some vague information about the action or the actor without actually saying who it was. So Nefersedjet might learn that it was a woman asking around and gauging the streets, or perhaps that it was a Copt or a Roman or a Jew. Gender and Ethnicity might easily be added to the system for these cases, my understanding is it would be quite simple to have the engine report: "You traced a level 0 action, but determine it was a Greek male responsible." Of course, a blanket application of that might lead to the character being easily identifiable if, for example, there are only two female characters or only one Persian character and the ST flag might be a less "stupid" approach.
Decisions decisions...
