Last night was the second and final play test for Lego FU, at least within the month of NaGaDeMon itself. The changes I made after the last one seemed to work well, so they're going to be committed to the document.
A surprising emergent property, though, was the replacement of the standard FU Conditions of Injured and Dying with No Legs and Disassembled. The players started the night asking, "I shoot at him. Do I kill him?" and moved to "I shoot at him. Do I disassemble him?"
The scenes of minifigs in pieces on the ground, trying to hop around and reconnect with their legs or trying to roll their heads around to reconnect with their torsos were interesting to say the least. All sense of blood-thirstiness vanished immediately, even though one player insisted on their minifig carrying the head of a captured bounty back to the bounty office.
This time I also remembered the Creationary box. It's hard to build something convincing in 60 seconds, it seems, and worked about half the time. I'll definitely leave that as an optional rule.
