Really enjoyed it, and agree with the other reviewers that the developers really nailed the Mad Max world.
It's not perfect; the are a couple missions that I had to replay too many times, the fighting can be equal parts exhilarating and clumsy, there are sloppy parts to the driving, I encountered several system crashes during the game, and the online component has been shut down. But you can buy it for a song now, and it gives you a lot to do and lots to upgrade and unlock.
It should be at the upper end of your backlog if you haven't gotten to it yet.
