Mods
You may create and distribute modifications, tools, or plugins ("Mods") for the game. By "Mods", we mean something original that you or someone else created that doesn't contain a substantial part of our copyrightable code or content. Ludeon has final say on what constitutes a Mod and what doesn't.
With regards to Mods, the following terms apply:
Your Mods must be distributed for free, period. Neither you, nor any other person or party, may sell them to anyone, commercially exploit them in any way, or charge anyone for receiving or using them without prior written consent from Ludeon. Commercial exploitation includes but is not limited to in-game advertising, other advertising or marketing for any company, product or service.
You may accept donations in connection with modding, but they may not be tied to the delivery of a specific product or service. You cannot try to push or force or pressure users of your Mod to donate to you in any way. Your request for donations must be unobtrusive.
You may not advertise for donations within your Mods themselves.
Your Mods must only work with the full, registered copy of the Software, not independently or with any other software. Your Mod may not be distributed together with the base game as a "modded version" of the Software.
Your Mods must not contain any illegal material.
Your Mods must not contain any material that violates copyright, trademark, or other intellectual property restrictions.
Your Mods must clearly be presented as community-created content and not as thought they were official or made by Ludeon.
Your Mods must not misrepresent what they are or their purpose, or deceive players in any way they wouldn't reasonably appreciate.
Your Mods may not be used as a vector for spreading malware.
Your Mods may not defame, attack, or bully any individual.
You own content you create. However, by creating any Mod or derivative work from RimWorld or making any content available on or through the Software, you agree to give Ludeon permission to use, copy, modify, adapt, distribute, and publicly display that content, for free or as part of a commercial arrangement. This permission is irrevocable and lasts forever. You also agree to let Ludeon permit other people to use, copy, modify, adapt, distribute, and publicly display your content, for free or as part of a commercial arrangement. This permission can be sold or licensed to anyone. Though we generally like to credit everyone for their work, we're not required to credit or acknowledge you if we use anything you created, or if we allow another to do so. If you don't want to give us these permissions, do not make content available on or through the Software. Please think carefully before you make any content available, because it may be made public and might even be used by other people in a way you don't like.
You're allowed to 'decompile' our game assets and look through our code, art, sound, and other resources for learning purposes, or to use our resources as a basis or reference for a Mod. However, you're not allowed to rip these resources out and pass them around independently.
