The folks at FFG have done a fantastic job in creating a solid universe for their Terrinoth setting. How the different races view each other, established histories, artifacts of power, creatures, etc. Well, isn't it time for all of that fantasy goodness to finally get its chance to shine as an established RPG? Fantasy Flight has shown how well the narrative dice system works with Star Wars and Warhammer Fantasy 3e (shame about the license btw), and they have plenty of experience in dealing with RPG designs, plus this is an IP that would be completely theirs which is always a positive thing.
As another positive thing, all of those minis people have for descent and the upcoming Rune Wars minis game would double up as minis for the RPG system as well meaning it would reward people who have supported their lines for years as well.
C'mon FFG, make it happen.
