I'm always going back and forth with the stats.
Quick is the first stat I wrote down. It has many definitions that work across several meanings, idioms and that famous "quick and the dead" quote used so many times in Westerns (where quick means alive, but in a gunfight could double as speed - the faster gun is alive).
Quick started as the Sharp parallel, but I moved it over to the stat used for "Seizing..." (which is actually more like "Claiming..." in Western world - to stake a claim, claim a life, etc...). But, Quick didn't seem right for "Going Aggro" so, I added Gritty and broke up those two moves.
Right now, there's two basic moves that are very similar to their AW counterparts (at the moment):
When you claim something by force... roll+quick.
When you threaten with brutality... roll+gritty.
However, something I've also considered is using Quick as the "Weird" parallel and making it something entirely different, though still used for the classic showdown. Essentially, making a showdown a distinct act that defines the setting somewhat.
I don't know. The stats are still in flux. Thoughts are welcome.
