Which line from the game do you like better, which is more closer to the deleted character Darkel from GTA III 
Niko - Playboy X - Dwayne 
I just love when Niko says "Playboy X, marks the Spot " 
Niko - U.L. Paper - Darko 
'''That special someone''' is most depressing scene in the game  
Johnny - Billy (Bill Fiore) Grey - Tom Stubbz 
Billy is the most badass looking character from entire game ,all this tattoos, gloves and sh*t. 
Louis Lopez - Bulgarin Molotov - Yusuf Amir 
I think mission ''Dropping In'' is a remake of the deleted mission from GTA III when you must kill Donald Love with a helicopter . 
Also it is obvious that Dimitry Rascalov is Curtly. Just look at this picture

Intresting connection like Darkel - Lenin, Bulgarin - Stalin.
