NOTICE
The following guide does not constitute legal advice. We suggest contacting a lawyer to ensure that you are compliant with any licensing issues.
This guide, instead, notes best practices for creating games based on the SCP Wiki. If the below rules are followed, we will consider that a good faith effort to comply with the license.
Licensing for SCP Games
When we're talking about creating a game based on the world or content of SCPs, we often get a lot of questions about how you need to license your game. Do you need to release it under a specific license. does it have to be free, does my game need to also be CC-BY-SA? Can I make an SCP game in Unity/Unreal?
Unfortunately, the Creative Commons license was not designed for software, and is not directly compatible with games; instead, the focus is on attribution, and ensuring compliance for derivative words or art.
To simplify how we talk about this, its easier to conceive of a game as three distinct parts: the engine and executable, the source code, and the assets.
Definitions
In the context of this guide, we are using each term in a specific way — to avoid confusion, we have defined these terms here:
Engine and Executable
The engine and the executable are two distinct aspects that we bundle together, because licensing considers them effectively the same.
Engine
The engine is defined as the base game development software engine that is used in the creation of your game. The engine refers to all of the proprietary code created by the company that created the engine, and is not considered relevant for the Creative Commons license.
Examples of engines include, but are not limited to:
- Unreal Engine 4
- Unity
- Godot
- RPG Maker
- Twine
- Scratch
Executable
The executable refers to the .exe file created when exporting your game from the game engine. The executable, similarly to the engine, is based on the proprietary code of the packager/engine creator, and is not considered relevant for the Creative Commons license.
Source Code
The source code of a game refers to all code, data assets, data-driven tables, mechanics-focused comma separated value files, or other forms of scripting gameplay (such as Blueprints, or other node based-editors). This only applies to code that was created by the developers, not including the engine or executable code, and is not considered relevant for the Creative Commons license.
Assets
The assets within a game refer to all non-code based files that are included with the game. The most relevant assets in terms of licensing are art files and narrative files, that are not natively packaged with the engine or executable — these assets are considered relevant when talking about the SCP Wiki's Creative Commons license.
Assets include, but are not limited to:
- Textures (.jpeg, .tga, .png, etc.)
- Models (.obj, .fbx, etc.)
- Videos (.mp4, .mkv, .avi, etc.)
- Music and Sound Effects (.ogg, .mp3, .wav, etc.)
- Narrative & Scripts (.txt, .csv (Narratives), .rtf, etc.)
If there is anything with meaning, appearance or otherwise that has been derived from the SCP Wiki, that you created for your game, consider it an asset — these items are the most relevant when talking about licensing SCP for your game.
Guide & Common Questions
Engine and Executable
To start with a common question:
Is there a restriction to what Game Engines I can use if I want to make a game about SCP?
Short answer, no.
There is no limit to what game engines you use, as any code that is used in the engine is licensed by yourself, as the developer of the game. Notably, the majority of the major paid game engines (Unity, Unreal, GameMaker) carve out an exception stating that you may publish your software under a different license than the engine, and that it does not change the license of the engine code itself. From this, we approach this entire issue in this manner; we separate the parts, and have the handled under different licenses.
Source Code
The next part of a game, and the next question is about the game itself:
If I release a game about SCPs, does it have to be under CC or a similar license?
While it is not required, if you wish to align as closely to the ethos of Creative Commons for your game, we recommend a similar license, such as GNU GPL, MIT License or GPLv3 — these software licenses have a similar approach to freedom of information that informs the reasoning and ethos behind our use of the Creative Commons license.
Assets
This is the section that directly relates to the Creative Commons license, and has the most 'complexity' to it. As defined in detail earlier, assets are defined as non-source code files created for the game, including but not limited to textures, models, narrative scripts, music and more.
How do I attribute the works? Do I have to?
When you are making a game that is directly using, or adapting an SCP work into a derivative adaptation, you must follow standard attribution for Creative Commons works. That means that you must include the name, author, and a link to the source for any works or derived from the SCP wiki that are used in your game — see the rest of the licensing guide for more details on that.
What about derivatives? Like a 3D model based on an art piece on the wiki?
If you create a derivative work, that is, any asset that is derivative of a work on the wiki, that asset should be released under a similar or compatible license. This means that, if I created a model of SCP-173 in my game, that model and texture would need to be released under a compatible license. This also means that said assets should be unencrypted, and available in the source of the game, once distributed/packaged in the executable — this is to ensure compliance with our works, as based on the CC-BY-SA license present throughout the site.
The also includes derivative stories; if your story is an adaptation of a specific work on the wiki, the narrative of your game should be released under CC-BY-SA, or a compatible license.
However, if your game is simply based on the concept of SCPs, but you have created your own unique narrative and anomalies, you would need to follow attribution towards the SCP Wiki, but would not be required to release those legally distinct assets under a similar license, comparable to standard licensing standards.
The Big Question
If you've made it this far into the guide, you're probably still wondering the big question:
Can I make money off of my SCP game?
The answer is yes, as long as you follow the ShareAlike license for assets, and have proper attribution.
Distribution is not controlled by the CC-BY-SA License, and as such, you are not prohibited from distributing that game for money.
Summary
In summary, when using the SCP wiki as the basis for a video game, you should ensure that your assets are compliant with the CC-BY-SA license. This, however, does not prevent you from using major game engines or profiting off of your game.
