I got my Platinum trophy last night =). Overall , I am really glad I picked up this game. It pushed itself back to the storytelling and engrossing world that SoT had. I also enjoyed the cell-shading. It gave it a nice touch to further distance itself from SoT and it fit with the world. I had a great time with the characters and the open-worldness. I only realized on my second play through that is was rather open and choice bound. The different bosses you face add obstacles that only appear after you face them. Each section has the potential for a lot of traps, making the difficulty of certain areas dependent on where you have been before.
I was a little miffed by the ending though. I saw some of it coming, but I think I was trying to blind myself because I was hoping they weren't going to do what they did. It felt a little trite. Maybe we are simply getting to what the rest of the tale he wanted to tell was and this is the only way to do it. Not sure where they are going, but I really hope they do something because I honestly enjoyed the entire game immensely, minus the last 3 minutes...
