Version differences[edit]

The Complete Edition[edit]

Retail DVD version[edit]

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[edit]

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.

Essential improvements[edit]

Issues fixed[edit]

DirectX issues[edit]

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[edit]

Caused by discontinued support for Python 2.3 in OS X Yosemite 10.10.
Copy Python 2.3 back into OS X[6]
  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.

  1. SafeDisc retail DRM does not work on Windows 10[3] and is disabled by default on Windows Vista, Windows 7, Windows 8, and Windows 8.1 when the KB3086255 update is installed.[4]
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/3900/ in addition to or instead of this directory. The app ID (3900) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
