First, we at GameNet love user modding and mods to our city building games and want to encourage you to mod. We see benefits for everyone involved.

The EULA and this Policy outlines under which conditions you may create and distribute mods of city buildings games. This Policy constitutes an integral part of the EULA by reference.

GameNet is not always the owner of the intellectual property into a game which it publishes, and therefore, GameNet cannot unconditionally allow modding to all games published by us. If you are unsure of which games are affected, please email

This Policy applies to all mods, including mods distributed through third party platforms such as Steam Workshop, and created by you.

  1. GameNet recognizes that you have a moral right regarding the elements of the mod which are your own original creative work.
