I have played about an hour past clearing Tutorial Island, and I have to say I'm very impressed with Far Cry 5.
It feels like a more mature game. The controls flow extremely well. The graphics are fairly amazing, capturing the feeling of being in misty wooded hills perfectly. The storyline is topical and serious, avoiding the over the top camp of the last few villains (which I thought worked once but felt like a rehash the second time).
Even the Ubisoft: The Game stuff has been toned down significantly. In fact, I was amused when I found myself climbing a tower and the guy on the headset made a point of telling me not to worry...he wasn't going to have me climbing radio towers all over the place.
Anyway, really great so far. It feels improved in similar ways to how Origin moved AssCreed forward, but in its own way.
