the dragon age RPG has a free downloadable Age of conan suplement
that is very well made . i'm curently runnig a campaign for it & my
player are quite enjoying it
There are several game systems adapated for play during the Hyborian Age. I can post several links if anyone is interested.
I am actually DMing one myself!
Originally it was going to be the d20 rules by Mongoose (2nd edition) but my original group did not find the classes very interesting. Now we run it in GURPS, with the fluff provided by the Mongoose books.
I've got a Conan RPG game going, too. My group finds the Mongoose rules fantastic. I love them, and I use them RAW (no house rules). I think the classes are perfectly chosen for the Hyborian Age.
My game's been running for about a year now, but we can't play as often as I'd like. The campaign focusses on two Cimmerian clansmen. Where as many RPGs feature multiple character classes and a party of adventurers, my game is playing out more like a real Conan story. Instead of the usual globetrotting, the tale presents two Cimmerian Barbarians of the Blue Fox Clan. I've created a sandbox--the Foxlands (their clan holdings)--for my PCs to explore and adventure in. We may one day leave Cimmeria, but for now, I've got my players real busy just living and breathing as Cimmerian clansmen.
I started the campaign with the PCs age 11, and ever so often, I skip ahead in time. We're slowly playing the entire lives of these characters.
Currently, the PCs are 15 and 16 years old, becoming accepted as adult warriors for the clan. They've made it to 3rd level (Mongoose classes), single classed Cimmerian Barbarians.
Interestingly, we're running it rather realistic for a game based in "Sword and Sorcery" literature, using various realism rules put forth in the GURPS supplements "Low Tech", "Martial Arts" and SJ Game's e-zine "Pyramid". My players even cared about buying and recording proper rationings for the road-trip they're taking.
My game is being run rather "realistically" too, though I'm starting to throw some "Sorcery" into the "Sword & Sorcery" mix.
I'll make a new thread detailing a new monster I've devised called the Demon's Breath. Look for the thread in this section of the forum. If you like what you see, you're welcome to nab it for your game.
