Pros:

-A beautiful setting
-Realistic geography
-Multiple routes to each goal on every level
-Delightfully frightening atmosphere
-Urges the player to explore
-Perfect difficulty
-A fun story

Cons:

-Only the very rare occasion when NPCs are nowhere to be found.(Not game-breaking, and not a problem)

Conclusion:

I had an absolutely great time with this campaign, and found myself lagging behind looking at the scenery or wandering through the many inlets and outlets of landscape. The maps had an entirely professional, realistic, and exciting feel to each of them in their own respect. This is easily one of the best out there.
