The original game was remplemented with new features such as a multiplayer mode via internet as well as the support for modern hardware. It also includes some smaller upgrades that are implemented as optional addons. To do that it was necessary to rewrite the whole game, but the original graphics and sounds are still being used.

Improvements towards the original game include:

• IP based multiplayer with optional UPnP port forwarding
• Support for higher resolution including a stepless zoom
• A new nation: the Babylonians
• New buildings: the charcoal burner
• Fog of war that shrouds the area when unexplored

You will still need an original "The Settlers 2 Gold Edition" version to play Return To The Roots.
