The definition of "yup, that's a good campaign. 7/10"
The graphics and environments look really good for 2015, makes it really fun to progress through the world. Gameplay and story are serviceable but has some good moments.
A rushed final area, technical performance needing a lot of fiddling, and not engaging "extras" (expeditions) make it a game with not much staying power.
PS: 100%ing it is also tedious - not worth it imo.
