Gameplay

Gameplay consists of undertaking and completing eighteen story missions while in the meantime performing various tasks such as taking over rival family holdings and carrying out contract hits. The missions are linear and follow the storyline of the first film, starting out with the player's recruitment by Luca Brasi after Connie Corleone's wedding and ending with the baptism of Michael Corleone's godchild during which the player plays an instrumental role in carrying out the killings of the rival family members. Similarly, the player also must contend with attacks from rival family members that increase in aggressiveness with the player's vendetta level, which is raised as the player attacks rival gang members and their businesses.
Players can increase their character's experience points, represented in the game by a "Respect" level. This level is increased as the player finishes missions or side quests or after interacting with certain non-playable characters. Increasing respect levels allow the player to increase attributes such as health and speed, while skills include fighting, shooting and street smarts.
A central part of the game is gaining control of local businesses, illegal rackets, warehouses, compounds, and transportation hubs. Each family has a controlling interest in the game's locales of Little Italy, Brooklyn, Midtown Manhattan, Hell's Kitchen, and New Jersey. The player accomplishes this by threatening business/racket owners. Racket owners can also be bought out. Each business controlled generates income for the Corleone family and the player's character. Pay outs vary depending on the effectiveness of the player's tactics and is made easier with higher "Street Smart" levels. Later releases of the game allow players to take over businesses by doing favors for business owners.
The player's ultimate goal is making his way through the ranks and progressing up the ladder through various titles (Outsider, Enforcer, Associate, Soldier, Caporegime, Underboss, Don, and finally Don of New York City).
