ExtrasThe UK edition of the game is said to include a novel by David Eddings 'worth 6.99£'. Either most people didn't like it and threw it away or it never was there; anyway it's definitely pretty hard to find.
Getting off a boatMost people playing the game for the first time faces the same problem: How do you get units out off a boat? This is not covered in the manual, and the words "How do I get off the boat?" is probably the most posted and joked about in the AoW-forums.
Highmen ThemeThe song "Highmen Theme" seems to be remix of Journey.umx which is played during the Nagomi Passage level ('day' version) in the Unreal mission pack Return to Na Pali.
