This is version 5 of the Age of Empires 3 update pack.
New features included are:
-Population limit is now 500! (Designed by Nicifer)
-Walls now make it harder to convert the buildings around them.
-The menu’s and loading screens now uses the Black UI.
-Fixed glitch where Ottoman’s could no longer train settlers after revolting.
-All Human units now heal slowly. This is to simulate the fact that people heal.
-Re-ordered units in Barracks since upgrades were not always in the right row.
-All civilizations can now build Transport Wagons.
-Flying Dutchman is added to the editor.
-New maps from the fan patch are included. (See credit below)
I had to split the file into two parts because its over the Heaven Games size limits.
For the 500 population limit to work, you must launch the game using the file “popmodlauncher.exe” located within your AOE3 folder. I suggest putting a shortcut to it on your desktop.
The Fan Patch and it's maps were created by Zutazuta of AgeSanctuary(Now RTS-Sanctuary).
They have graciously given me permission to use features from it.
