The ending's subtle metaphor
(Spoilers Ahead)
Just finished Mafia 3 once again and only now do I realize that Sal Marcano's death is metaphorically written as Lincoln throws him from the top of the Paradiso Casino. The word 'Paradiso' stands for Paradise in Italian, so he's depicted as falling from his version of Paradise (that is physically embodied as the casino) due to his pride and ego.
Don't know if that many players gave it a thought but I was bored and made this connection in my head.
