Version differences

The Complete Edition

Retail DVD version

The Complete Edition contains the base game, Warlords, Beyond the Sword, and Colonization on a single DVD. It contains an updated DirectX installer and contains no DRM. The individual games still require patches to the current version.

Steam version

The tutorial for the game is only available through the base game installation, and the Warlords expansion contains exclusive scenarios which are only available through its installation. All other gameplay contents and features are included in Beyond The Sword; if you do not need the base game tutorial and Warlords scenarios, you may uninstall them respectively. Colonization is a standalone game which does not overlap with Beyond The Sword.

Issues fixed

DirectX issues

To ensure the original game and its expansions run properly, install the latest DirectX End-User Runtimes. This is not a problem with the Complete Edition, which installs the correct DirectX version automatically.

Failed Initializing Python

Caused by discontinued support for Python 2.3 in OS X Yosemite 10.10.
Copy Python 2.3 back into OS X[4]
  1. Download BTS YosemitePython Fix.7z.
  2. Copy the folders '2.3' and '2.5' to /Library/Python/. Enter your administrator password.
  3. Go to /System/Library/Frameworks/Python.framework/Versions/ and delete the alises for '2.3' and '2.5' and copy in the '2.3' and '2.5' folders from the BTS Yosemite Python Fix.
