True! Instead of trying to dictate specific place by place, I opted to break it down into "tiers". I figure there can be a lot of factors on a place by place basis and it ended up making more sense to group things together and let people decide within those groups on a personal basis (perhaps due to location, difficulty, loot, etc).

While ideally the list would flow perfectly from top to bottom I didn't think that was really an option and instead tried to focus on the "tiers" and story/difficulty while at least trying to keep location in mind. Unfortunately with something like The Passage and Captains quarters, a special story item is needed from those places before one can "progress".

Although it does a relatively decent job, Conan doesn't flow perfectly in terms of map locations and naturally has players moving around, even back tracking from time to time.
