Also known, tongue-in-cheek, as Ragnarök World. At first it was pretty much a straight hack, with character playbooks/kits and all, but then I tore it apart, rewrote and now I'm here:
my working documentIt's still very rough around the edges, stuff missing. I've been trying to come up with far too many new moves to be honest, because this was actually an original game I was working on, which I then adapted to AW, and it's a bit hard to reconcile the two in places. Hasn't been played yet, and I think I did as much as I could without further feedback and playtesting.
I think there's some cool subtle stuff taking shape in there, even if it's still a mess in other parts.
