Picked it up at 3 AM last night. I'm really enjoying it; I particularly liked unlocking the Twins Gang outfit: explore Thieves Landing, win at horseshoes, protect the ranch from a gang attack, capture a gang bounty alive, buy a scrap from the Thieves Landing store—pretty sure there's one other requirement, but I can't remember what it is.
Only downsides so far: just had the game crash to dashboard, which isn't something I've ever seen a game do before, and it's often kind of tough to figure out who's good and who's bad in those little situations you stumble on. I've accidentally earned a bounty during a stagecoach hold-up, a murderer shooting people outside the saloon in Thieves Landing, and when I was trying to stop a hanging along the road between the ranch and Armadillo. I think it may partly be that my TV's kind of terrible. Which reminds me! Developers: please include a screen adjustment option in your games! It makes me sad that text along the top and bottom of the screen is cut off.
