For reasons not entirely clear to me, I have never reviewed a Year Zero game. The Year Zero engine is Fria Ligan’s centerpiece, and maybe even their house system as well. Named for Mutant: Year Zero, the game system powers designs as widely varied as the Alien RPG and Tales from the Loop. And now Free League Publishing’s Vaesen. Vaesen is new territory for the Year Zero engine and indeed mainstream tabletop RPGs in general, being a game of fairy tale horror and specifically Scandinavian fairy tale horror at that. While fairy tale horror may not seem like the most natural fit for a system better known for maps, bases, and colored dice, Vaesen ends up being a pretty wonderful take on the system, its juxtaposed strengths working well provided that you buy into the high concept.
