A CHM version of Age of Empires Help File (Empires.hlp)
It includes Rise of Rome Expansion Help.
The history of civilizations in RoR is not similar to ancient cultures in AoE (structure: overview, Location, Capital, Rise to power, Economy, Religion and culture, Government, Architecture, Military, Decline and fall, Legacy), so I do not include History topics in this help.
The help has a lot of hover links, some of them will show amazing animations if you hover over these links.
Enjoy!
Does not work for me, on Windows 10.
I extracted it to the AoE folder. The CHM file opens in the Windows help viewer, and the index shows in the left pane, but no content shows in the right pane when I click on the items in the index.
