Actor Allusion: Sometimes when negotiating with a street dealer Tony will say "Make me an offer I can't refuse." Given how Tony is depicted as a big fan of American movies, it is also completely in character for him casually drop a Godfather quote.
André Sogliuzzo voiced Tony in The World Is Yours, although Al Pacino's likeness remains. Being a frequent understudy of Pacino on stage, Sogliuzzo was a natural pick by the man himself to be the new Tony.
This is also inverted numerous times with some of the supporting characters, who were played in the movie by relative unknowns only to be replaced by more famous actors in The World is Yours:
James Woods takes on the role of Tony's lawyer George Sheffield.
Cheech Marin takes over the part of Gaspar Gomez.
Michael York is Jerry, Tony's banker.
Miguel Sandoval is Nacho Contreras.
Vocal Evolution: The reason why Al Pacino did not voice Tony Montana in The World Is Yours. He attempted to re-emulate Tony's accent, but both he and the developers felt his voice had changed too much to properly pull it off (Said attempts also put a heavy strain on his vocal chords because the accent was too hard to pull off). Pacino handpicked André Sogliuzzo to play Tony instead, though his likeness was kept.
