Not at all what I had hoped for, the Xbox 360 deserves better!
To be honest, it looks more like a standard Xbox game and not a next-gen game for the best console on the market right now.
I wonder if the game was rushed out so that it was available at launch as the visuals look a little rough around the edges and sometimes even blurry and the gameplay swings from 'great' to 'what happened there.'
On a positive side, the voice acting is fantastic and adds to the games atmosphere. Riding a horse is fun, once you have mastered it and the shoot outs are fast and furious.
There is way too much swearing in the game, more than is needed I think and I did not know that so much blood in a body.
Gameplay wise, it is a short game and I completed it in about 10 hours. The story is not too bad although it does seem to go all over the place but comes together in the end.
As this is the only game of it's type out at the moment for the 360, there is nothing for it to compete against but I would probably be tempted not to buy it but to rent it.
