Just Cause 4 is an entertaining game to play if you want to just sit back and blow a bunch of things up. The new customisation options are great, and there are some interesting ideas with extreme weather, but ultimately a lot of the missions arent particularly exciting or ask for you to vary up how you approach them.
If you enjoyed the last game in the series then Just Cause 4 will give you a lot of fun creating explosions across the world, it just doesnt push the series in any meaningful direction.
