No one wants to play in a realistic, stench filled, disease rotted, life expectancy of 28 type of RPG man - we want the freaking Hyborian Age - we want Robert E. Howard type legendary sword & sorcery.
We want hideously contrived false dilemmas!
Oh no, wait...
No one, bar you, has suggested adding stench, disease of anything like that to Conan. The most anyone has said is that if you are running a game in the Hyborian Age, or immersing yourself in it any other way, and you take the background even slightly seriously the fact that Conan has more than one account of his birth and early life requires explanation.
Added to that, you appear to be under the impression that any addition to Conan's tales improve them. When I see a "Conan" tale that has him acting like a wangst-ridden naval gazing incompetent, or has him sieze a throne and then decalre that he is not worthy of it and ride into the sunset, instead of taking that kingdom and turning it into an EMPIRE, then I am quite happy to punt them out.
