Shameless plug for Numenera, the new story-driven game from Monte Cook. All of the skills the Dungeon World taught me transfer perfectly to Numenera! I’m taking a break from Dungeon World to get a little more mechanics for my players (from their own request).
But, I’ll keep using the setting and monsters for Dungeon World. This is the only game I know where Monster creation is easier than DW.
TL;DR Highly recommended, in a very similar vein as *World games, but with a bit more of a mechanical feel. AND I get to use my d20s! I missed those guys.
