Kick ass, Cowboy style.
The story was good, and the action was amazing and fun. The side quests were many and varied, keeping it fresh. And I have to say, the final boss was good too. It wasn't just another boss with a health bar, there was a specific way to injure him, which made it hard, yes, but it was different, and I have to give a nod to Neversoft for making it different, even if it wasn't perfect.
Overall there isn't much replay value, unless you didn't do many side quests, but it was really fun. I highly recommend it to all action game fans. Don't miss it!
