Patrick Bellanca, Assistant Designer for Madden NFL 12, has released a blog detailing the changes in Superstar Mode.
"The instant you get into Superstar mode, you’ll notice the entire interface has been redesigned to match the visual style of the rest of the game. The main hub has the same menu style as Franchise mode and Online and should already feel familiar. From the hub, you can always see your superstar, dressed however you set him up, as well as his key stats and attributes. From here you can navigate to the depth chart and monitor your progress toward the starting job. You can still choose to play as an NFL rookie from the 2011 NFL Draft, or import your NCAA Football Road to Glory player. I’ve always preferred to create myself to live out those football dreams. Every year we add new equipment to the player creation process and this year is no different. Quarterbacks look more realistic that ever this year because we’ve added flak jackets and back plates which are available to you. The side by side before and after comparison photo of Eli Manning is stunning, which I think Mike Young published in another blog on Presentation and Graphics."
