Very good overall. Some comments:
Section Maelstroms:
Maelstroms close reef features and fishing zones
Maelstroms divide fishing zones and reefs end at a maelstrom?
Section Hurricanes:
- The text of the first paragraph is not justified.
- NPC is a gaming term. The Big Box 2 calls those "neutral figures"
Section Leviathan:
The leviathan eats any follower or support follower it crosses in its movement. Return the eaten follower(s) to its player’s reserve. The leviathan also eats Khayr.
By eats do you mean remove? Or does the leviathan have a special action feature that it can swallow stuff into its hollow body?
Section Ocean Trade Simple Example 1st para:
- "point-to-point" is missing the hyphens.
- "When a merchant reaches a new harbour with it’s goods, it immediately scores according to the chart at right." The "it's" there looks funny - I have no idea whether it should be with or without the apostrophe. It reads better if the word was deleted completely, i.e. "with goods".
- "Count
the tiles from the trade marker using the most direct path, over islands if possible." The word "the" is missing.
Section Disaster! - Scurvy, rats, and bad food
- "This chosen follower is removed from the map and is returned to it’s player." The apostrophe should be deleted.
Section Pirate Sanctuary
- "In that case, the pirate claims in all four directions." claims
the reefs?
I'm still a bit confused about Ocean Trade. Do you think you can provide an example for the simple rules?
