Hero
never did a whole campaign, but I did do a couple of one shot Viking ones; one, where they went to England and fought the Black Worm of the Barrow to get some magical doodad, and another where they went to Long Island in pursuit of a renegade who had taken refuge with a tribe of Skraelings led by a verbeeg war-chief...I ran a few games in those eras and a whole campaign set during the Crusades with the Green Books
