Seconded. Well, in fact "sixthed" I think, but you know what I mean. Its probably an prejudice of mine that I associate Runequest with grittier, low fantasy (but still great) games... Mainly the fault of Havercake Lad's various Elric campaigns. Thieves World itself accomodates both the gritty and the heroic approaches to fantasy pretty well, that RQII/Wayfarer would be an excellent fit.
