Stepping out on a limb here...
I've been messing around with this Old West hack of AW. You can find it
here. It's not quite complete, but I have the following classes (some of them are a little weak, so help me improve them!):
The Trick Shot -- fastest gun in the west. This guy is into making a name for himself by winning showdowns. He's also pretty wicked in a fight.
The Law Man -- the marshal or sheriff. This guy organizes a posse and goes after people to serve warrants against them or collect the bounty on them.
The Gambler -- the con man; the face. This guy is always in and out of schemes, cheating folks to get rich quick.
The Thunderheart -- the Indian brave slash shaman. This guy can disappear into the wild without leaving a trace. He's also got some quasi psychic open-your-brain stuff.
The Outlaw -- the Chopper, pretty much. The outlaw has a gang, and the wild lands between civilized steadings are his domain.
The Baron -- the Hardholder, pretty much. A town has built up around this guy's enterprise (eg, his mine or his railroad). There might be a sheriff and a judge, but they default to his authority.
The Madam -- she has the dirt on everyone, and she trades in secrets and social favors. If you need something and you don't know how to get it, she's usually the one you want to see.
The classes are a mix of adaptations from AW plus my own moves plus moves I've seen floating around on these forums (eg, I know I stole moves from John Harper, and from the Smiler, the Abacus, and the Cabal, just off the top of my head). If anyone sees a move they invented and has a problem with me shamelessly stealing it, let me know and I'll pull it down from the document.
We haven't playtested this yet (mostly because my group has had a hard time getting more than 3 of use together at a time for the last month). We'll probably playtest it starting in late November. But I really wanted to start getting feedback on it, as I've only had limited experience hacking AW before.
So please, play it out and let me know what you think.
