Alright, so here's a project I've wanted done for a long time. This likely isn't complete, as there are several diseases I could include here, and when I rework the psychic diseases and finish up my medicine rules, some of these might change, but the final version will be on the wiki somewhere.
This is essentially a "worked version" of the rules I posted yesterday. Those rules work fine for a modern world setting, where you can talk about "Cholera" and "the flu" but what about when you're in space? Well, then are we talking the Andromeda Strain or the Purple Polka Dotted Pox? Some names to toss around might be nice, and how disease shapes the setting might be nice to know as well.
In particular, the Umbral Rim is famous for its diseases. This comes from the fact that it has filthy aliens in it, but it also comes from the presence of the Gaunt, who often act as carriers, and even have a special trait for it. When I started working on them, I wanted a list of diseases to introduce, but that proved too much work. Well, now I have it! They can give you anything from the Umbral Pestilence to the Centauri Sniffles!
I've also included "Terminal Illness." I like the idea of a Terminal Illness: there's a dramatic weight to a heroic character that is dying of cancer and knows it. I do agree with critics of the disadvantage that point out that it hardly matters to the player when the character dies, as they'll just make a new character and keep playing. However, having cancer (or leprosy or tuberculosis or AIDS) might shape other things about your character, other disadvantages that you can explore. So the terminal illnesses here treat "time left to live" as a feature: Your character will die at some dramatically appropriate moment that you and the GM both agree to. But in the meantime he'll have a persistent cough or he'll have open sores or he'll have moments of intense chest pain, etc. These are just disadvantage bundles to give your character some in-setting disease or illness.
I did need to play with some disadvantages to make this work, though. The first was Chronic Pain. I like the idea of it, but I find it limited. Mild pain is effectively the Moderate Pain affliction, Severe Pain is effectively the Severe Pain affliction, and Agonizing Pain is effectively the Terrible Pain affliction. With some wiggling around, it seems reasonable to substitute other afflictions: what about a Chronic Cough? That's basically the same as Mild Pain, and so is worth -5 as a base.
The second was Cardiac Stress. The idea here was that we could treat the limitation as a straight disadvantage. However, Cardiac Stress assumes the character is using something. What's he using if we give it to them as a raw disadvantage? Everything? So I said "if you're under stress" and took the limitation value and halved it as a disadvantage value. It's a back of the envelope guess here.
