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.
