Oh, come on! Diseases just plainly suck. It\'s the same thing as why bleeding to death isn\'t implemented. Instead, you slowly heal (even without any treatment), which is totally unrealistic, especially if you have only 1 HP left. If a disease would kill you, you\'d have the same effect, just without any chance of avoiding it. I know it\'d be realistic, but I think it would remove more fun than it would add, and therefore should be left out. Imagine having to visit the death realm on a regular basis... yeah, sure, healers could cure you, but so can they cure wounds that would make you bleed to death, yet they don\'t kill you. Therefore, you\'d have to give players curing spells for these diseases so that ppl. can actually keep going on long distance travels.
Anyway, if you become immune to the diseases, you could probably try to get them all as quickly as possible, to be not bothered by them afterwards. It would be like a low-level quest grind: keep dying of all diseases until you\'re immune to them, then start gaming.
Anywa, how about merchants, who come into contact with loads of ppl. regularly? Will htey all die regularly?
I think that if this is implemented, it needs serious tuning, and I don\'t actually see an increase in fun to make it worth the effort. I mean, the aim of PS is adventuring, not staying alive. It\'s the same reason why you don\'t die of hunger in RPGs: the tediousness detracts from the fun, which is a bad thing.
