Finished it a few days ago. It's pretty damn good. If you liked Ico I can't imagine why you wouldn't like this. The first few hours or so while you're getting acquainted with everything is ok, but the last half of the game is where it really shines. Trico truly feels like it has a life and mind of its own rather than just being a mount that follows your every commands. It can be frustrating at times, but honestly I think you wouldn't have such a strong bond with him if it was any other way. I know it took a zillion years to come out and I think there are real issues with the controls but I was still very impressed with the game overall.
