Mmmh, playing my first RD game and Death rate is fine so far. It is more than before, but it feels right that way (not because I don´t know the infant mortality statistics stuff, more so it feels pretty realistic). I get sick about three times a live, which is, concerning my actual live experience in the 21st century, a good number. My first character died with 57 on cancer, which sounds reasonable, lost one child to the flu as teenager and one (-> Which was my sister then) to cancer with 27. One brother had a sudden infection with death, but that was poisoned wine I gave him.
Looking at my suuroundings:
I am pretty heathy, but I would be dead in the 8th century on my liver and I would be maimed concerning a little accident with a scissor in my 20s, which is fine today of course of medicament and an operation. My girlfriend would be dead on an allergic shock, one of my best friends would be crippled due to a skateboardaccident, my mother would have lost her eye, my father would be dead of a heardattack in his 50s. I don´t know many people who would be alive by now without the medical treatment of the modern times.
Don´t get me wrong, I know that the people didn´t die like flies back then, but in my game so far it feels quite right.
