Man, there is so much lateral thinking going on here. If I talked about every mechanic I thought was cool, I'd write like a page-long comment, lol. The idea of Havoc as a competitive rather than a cooperative game is fascinating. I found voting on turn order really interesting as well. The skeletons are so mechanically distinct, every one of them has an amazing amount of creative ideas and hacks crammed in there. The basic rules are concise and straightforward, with really great retheming of the Havoc mechanics, but I did have a couple of confusions; first, are the skeletons rolling a vendetta for every NPC they meet, or just the ones they roll for when entering new locations? And second, how is it determined which NPC is rolled? They're not numbered.
Awesome derivative work with the public domain art. I love memento mori/danse macabre pictures.
