Only played a game or two. I like the random initiative mechanic which was pretty fun. We used playing cards. Rules seemed pretty solid and worked in the western elements, ie showdowns, horses, wagons, etc. I also like that models degraded as they took damage.
Not too much negative to say. Not a big deal but I didn't care for only having one stat for everything. I like a little more fleshing out in the character department. I advise having some kind of scenario planned when playing. The combat can be rather deadly and our straight up shoot-up turned into a point-blank-shoot-em-in-the-face-fest. Fun though!
