One character was removed from the final version of the game. Yet the character names are left in the book, and in the game's credits, named Darkel. There is nothing left of him in the game except for Darkel's character skin, who appears to be a hobo / homeless person. Two popular ideas about Darkel's removal are: 1) He gave terrorist like missions, and were removed due to the 9/11 attacks. 2) He gave you the rampages, but the company decided the traditional skull icons would be better. Darkel was voiced by Bill Fiore.

The game was temporarily removed from sale in Australia, for re-rating. The objectionable content was the player's ability to collect a prostitute, who would sit in the car's passenger seat; if the car came to rest in a secluded area, it would begin to rock violently, implying sex (although both characters remain, unmoving, in their respective seats and stare forwards). What made the content objectionable for the Australian Censorship Board is that you could kill the prostitute after the act was done, therefore deeming it "sexualised violence". A censored version for Australia, removing this ability, was thus released, as was done for Grand Theft Auto: Vice City (2002).

Originally the police cars were going to use the NYPD blue and white paint scheme. A few screenshots of them can be seen in the map/poster that comes with the game (the best one is right under the word "Liberty" in the title "Welcome To Liberty City"). It is believed that the police cars were changed to the standard black and white paint scheme to make them not look like the NYPD cars because of the terrorist attacks on the USA of 11 September 2001.

Around the city, there are numerous spoofs to movies and Broadway shows. They are: "BadFellas", which is a spoof of Goodfellas (1990); "Fannie", which is a spoof of "Annie"; "Saturday Night Beaver", which is a spoof of Saturday Night Fever (1977); "Duck Pond" (from Liberty Ballet Co.), which is a spoof of "Swan Lake"; "Rats," a spoof of "Cats"; "Half-Cocked," which could be a spoof of cop movies, such as Dirty Harry (1971); "Top Down City," starring "Arnold Steelone", which could be a spoof of Arnold Schwarzenegger & Sylvester Stallone action films (it's also a reference to Grand Theft Auto, Grand Theft Auto: London and GTA 2, which all featured a top down view) ; "69th Street," a spoof of "42nd Street"; "Soldiers of Misfortune," a spoof of war films; and "Pirates In Men's Pants," a spoof of "Pirates of Penzance."

In the opening cutscene, three prisoners can be clearly identified: the protagonist, 8-Ball and the old oriental gentleman - a friend of Donald Love. He is broken out by the Colombians to hold Love to ransom. Love has you rescue the old oriental gentleman from the Colombians custody in the mission 'Liberator'. The irony is that the protagonist's constant enemy, the Colombians, unwittingly helped him escape and begin his revenge on Catalina.

The fate of Donald Love after his disappearance is not known. Love's only other appearances are in Grand Theft Auto: Vice City (2002) in the year 1986, and in Grand Theft Auto: Liberty City Stories (2005) (VG) in the year 1998; both set before the events of this game, in 2001. With Grand Theft Auto IV (2008) being set in 2008 and essentially being a reboot of the GTA series, with no recurring characters (except Lazlow), Love's fate is unlikely to be ever resolved.

In the mission 'Waka-Gashira Wipeout!', Donald Love quotes his former mentor Avery Carrington: 'Nothing drives down real-estate prices like a good old fashioned gang war, apart from an outbreak of plague... but that might be going too far in this case.' Love then sends the protagonist on a mission to start a war between two rival gangs so the property values in the area will go down. In Grand Theft Auto: Vice City (2002) - which takes place 15 years before - there is a similar mission, 'Two Bit Hit', that Carrington gives Tommy Vercetti. When he gives Vercetti this mission, a young Donald Love is present as Carrington's protégé. Carrington tells Love to pay attention as he might learn something, and then utters the original quote.
