Absolutely worth it
It's a 3rd person open world action game set in the Mad Max world. It plays similarly to the rest of the genre, so if you like open world 3rd person action games you should like this. It's melee focused, so there's not a lot of gun play. Think of it closer to the Arkham series than Far Cry because of the combat.
What sets it apart are much better driving mechanics than others in the same genre (which makes sense given how important vehicles are in Mad Max). It also has regular sand storms which add some variety to roaming the map.
It doesn't do anything that different when it comes to 3rd person action. Everything has been done before, but this game does it well IMO.
