I think the idea to have an save game episode consequences system like Mass Effect is already protected by patents under Electronic Arts as they did file patents for games like Mass Effect, because I know their mouse wheel dialog system is protected under patents and that there are patents to cover everything from the game mechanics, the models used, the game textures, the shaders of the engine, the episode game concept, the textures, the rigs, the shaders, any new invention or idea used in the game like the player model face generator system, you can’t re-create these ideas and concepts into your own games unless they give you permission to do so, I think that’s what it means. but check with them first before you go ahead with the game.
