I haven't played the main game, but from the gameplay videos I've seen on youtube, the graphics look the same to me. And they are incredible. The gameplay is a masterpiece, there are no words. The environments and characters are very well done. I can't say the same for the story itself. I would still describe this game as "play and forget". It doesn't seem to have any replayability unless you fall in love with the game. I didn't plan to finish the game again after I learned everything about the story and plot, but I did replay the first episode to see how the new game+ was.
