If they were making Sonic Unleashed again, SEGA would need to start from scratch. I found that Sonic Unleashed was the third worst Sonic title of all. Unresponsive controls, terrible level design, and a poor camera angle are just the beginning of the problems in that awful adventure. It did have a great nostalgia to it though. Maybe it could work if someone made a game LIKE it. Just not an HD version of the same awful experience.
