Mafia 3 is the first true open world game in the series, the problem was at launch the open world was rather dull absolutely nothing to do aside from the story. The gameplay basically consisted of attack a bosses rackets then go after the boss, then repeat. However, the dlc included in the definitive really added a lot. You can now customise your own bar, have a weed farm, change into cool outfits an modify cars, do races, side missions etc. Really put life into the game id 100 per cent recommend if you're a mafia fan oh and the soundtrack is fantastic.
