I watched "Scarface" last night, which is the first time I'd seen the film. The message of the film is delivered fairly early on, from Tony's first boss, which is "Don't want too much." Tony, of course, wants everything, which sets the stage for his spectacular rise and fall.
So, now I know the scene behind the "Say hello to my leetle friend" quote, and I also realized that much of GTA: Vice City was, in fact, an homage to Scarface, including the mansion that eventually becomes your home base.
I also wasn't aware of the apparently-famous "Cuban crime wave" that forms the backstory for the movie -- Casto decided to take advantage of the U.S. open-borders policy on Cuban refugees to clean out some of the scum that had been clogging up his jails, and dumped some 25,000 hardened criminals on Miami. Clearly the law of unintended consequences was in effect.
