As a Gm i have a tendancy to include the odd Nordheimer here and there. One of the most memorable gaming sessions we had was the characters fraternising with a half a dozen Aesir mercenaries in a tavern in Gunderland. With no real combat except a few friendly wrestling matches one of the players managed to roll 13 natural 20's! That red-headed Zingaran piratess showed up a whole lot of Barbarians and Soldiers. Beating them at arm wrestling, drinking and a whole bunch of gambling games.
As a player however i have too many character ideas i want to try out to say what my favourite is, although straight up Hyborian is pretty reliable when you cant decide just what to play at the time.
