Apart from Bastion, unpopular opinion I suppose, but the 2008 Prince of Persia was one of the most beautiful games I've played. I recently replayed it and the cel shaded graphics still hold up fairly well. The story, especially the ending, is still great. I think most people didn't like it because it was a very different game from the preceding Sands of Time trilogy, but I treated it as its own thing, and loved the fuck out of it.
