Gaming Ballistic is in the final 48 hours of his kickstarter for his Dragon Heresy Introductory Set.
Dragon Heresy is a Dnd 5e variant that is a gritter take on the fifth edition mechanics. In addition the setting he created for his RPG has an interesting take on Norse mythology and culture.
Currently I am running an Adventures in Middle Earth campaign. The experience had lead me to conclude that Mearls and his crew did an excellent job of designing an RPG that can be adapted, with tweaks, to radically different settings and sub-genres. Dragon Heresy is another excellent example of using that flexibility.
Head on over to the kickstarter and listen to Doug's pitch and see if it something that interests you.
