-There will be LEGACY RATINGS to achieve from "Bum", "Prospect", "Club Fighter", "Contender", "Champion", "Superstar", "Hall of Famer", "Ring Legend" and "Greatest of All Time"
-These Legacy Ratings will have several achievements that each fighter will have to satisfy to move to the next like: win percentage, popularity level, rank, number of fights, televised/PPV events, winning titles, defending titles
-These achievements can be changed/tweaked by the user in Legacy Setup.
-Quick KOs will earn you more popularity. Longer 12-round wars will help you more in stats and can be rewarded with rematch request.
-There are ESPN Pay-Per-Views that fighters can fight on undercards or for main events.
-There are eight weight classes to fight in. Flyweight, bantumweight, featheweight, lightweight, welterweight, middle weight, light heavyweight, heavyweight.
-Each weight class will have 3 separate belts to win. One of which is called the EABF. It's logical to assume the other two are called the EABA and the EABC(or EABO).
-User fighters can move up weight classes. AI fighters will also move up and down weightclasses as well.
-Rilvaries in Legacy Mode are more fluid and sensible than in Round 3's career mode. In other words, if you and a AI fighter fought at welterweight in a 12-round battle, then it is likely there could be a rematch(or rubbermatch) in the middleweight division.
-There are rankings for each individual weight class as well as an overall pound-for-pound ranking.
-12 User CABs(Create-A-Boxer) can be supplemented into Legacy Mode at set up.
-"Legacy Central"(Legacy Mode main screen) will allow users to schedule their next fight, view their last fight(not watch), get advice from their trainer, view their popularity, rank and pound-for-pound rank.
-When fights are scheduled, it's done on a "Fight Calander". Each fight, when scheduled will feature several days preceeding the bout for training camp.
-There are six training games to choose from: "Open Sparring", "Stay on Your Feet", "Heavy Bag Combos", "Heavy Bag Push", "Double End Bag" and "Maize Bag"
-Each career in Legacy Mode begins with amateur bouts, which can be skipped.
-You can be called out by rivals or you can be pick or select lesser skilled fighters
-You can create your own fighter or use a fighter from the roster in Legacy Mode.
