The game developers decided that Al Pacino's current voice was "too old" for this 30-something character, so they gave him full control over his substitute instead, as a part of the "voice and likeness" agreement. This very same agreement also prevents Pacino from lending his voice or likeness to other film-based games, which is why he's not included in the cast of The Godfather (2006). André Sogliuzzo was handpicked from a vast selection of voice artists by Pacino himself, to deliver the voice of Tony Montana - who of course was played by Pacino in the film the game is based on, Scarface (1983).
Tony's fortune at the start of the game (which he eventually loses) is $65,884,703, which is the same amount Scarface (1983) grossed worldwide at the box office (unadjusted for inflation).
The video game is a Alt Version to Scarface (1983) which Tony Montana doesn't get killed in the mansion battle with Sosa's army of killers.
The game holds the Guinness World Record of 'most swearing in a video game', with 5,688 f-words throughout its 31,000 lines. (Checked April 24th, 2020)
