Picked this game up today (it's for PS2) and I must say it's one of the most visually stunning games I've ever played. It feels like you're playing a movie the entire time and when you're facing a 100 foot tall boss that you have to climb it's definitely one of the best gaming moments in the last few years. The game takes place in a huge desolate land that you travel across on your horse. There are very few structures but the landscape is amazing. I found myself riding around just taking in the world that they created for the first few hours.
