It introduces a few new concepts such as city districts and world wonders that actually occupy land tiles in your cities and that benefit from adjacency to resources or other structures. If you're into turn-based strategy games then you should be happy to know that Civilization VI also works on Macs and that the game is actually pretty great. The only thing that was a bit disappointing was the end fight, but you'll have to find that out for yourself. Despite the fact that it can seem a bit repetitive at times, this game has it all: shootings and explosions, badass car customizations and different looks for your character.
The storyline is well conceived, the graphics are great and there's plenty of action. When it comes open-world GTA-like games, I could have gone with Mafia III, but I preferred Mad Max because this game didn't have the right to be so good and it actually surprised me.
