- In the 4.0 intro section 4th paragraph 2nd sentence "Empires that allow empires ..." um, is this supposed to be "Campaigns that allow empires ..."
- 4.2.1 4th paragraph, this paragraph about Sector Lanes in Sector Maps feels confusing an out of place, Sector Lanes have not been mentioned before so it's hard to relate them to the Galaxy Map at this point
- 4.3.1 Final example, the target system being not valid and thus creating a Sector lane does not really make sense how you got there with the rules before. The target system is greater than 40 so it's a sector lane in the example but the rules say sector lane if greater than 50
Two other things I really liked in Maps rules are the way System Maps are constructed make them really easy to visualize the system and the planet layout, and I do like the name of the next planet past Pluto, Makemake
