It is a great game. I felt like there was a slight bell curve in terms of enjoyment - things definitely get much more fun as you power up your fighting abilities and your car, but it starts to get a touch samey after a while. Nevertheless, I've spent many pleasureable hours driving about, ransacking sites for parts to upgrade camps, doing the odd mission, ditching the odd scarecrow. God of War 4 has taken me out of the Wasteland for a time, but I'm looking forward to going back to finish the final 40% or so.
