Yes, this is a game mod, and the author of the mod does not exercise intellectual jurisdiction over the game, but to a certain extent the content of the mod is that author’s original work. By not including the game mod link in your description, you are deny the mod maker recognition for their work. [quote=“Tyler_Moore, post:23, topic:9759”]
I am not making any money using the mod. I am making money off the game.

This statement is not entirely correct. You are making money off unique gameplay, originating from a mod, which sets you apart from the many other YouTuber’s making GDT videos. In order to properly credit all parties responsible for the creation of the unique game that you play (i.e. not a vanilla game, but a modded game which is different from other copies) you must credit both the developer of the original software and the developer of the mod which made your unique gameplay possible. Also, the components of the base game are not wholly developed by the developer of the game, not unlike modding, Greenheart used many libraries and tools in order to make GDT possible. Much could be learned from GDT’s own credits page, which gives links to all others intellectual property.
Making our own website is not a tough task right now. There are several platforms like WordPress out there where you can easily create your own website without any hassle. Also there are several online tutorials and discussions out there by which you can easily make your own website.

No it is not. What authority do you have to curtail my free speech? Might I remind you that your original comment was:
That does not say “I’m listing the mods in the description”. It says that you believe that the mod is not important enough to be cited as a feature of the gameplay. Might I mention that you only relented to the position that you will only list the mods upon a backlash from the very community that you are attempting to market to. Do what you want with your videos, but , you will not be fully giving credit where credit is due. If mod makers are not credited for their work, which you are potentially making money off of, there is not an incentive to make mods anymore. Personally, I will never visit or subscribe to a channel which does not fully cite those responsible for it’s original content.
Jesus mate just link this page to your videos it isn’t that hard. The time it takes for you to link this fourm post doesn’t even come close to the time he spent working on this for free
linking a person’s mod is a matter of simply copying a link and pasting the link you copied from the mod page into the description and so what if its not the hardest to make this type of mod its just feels good when somebody gives you credit for the work that you have created
would anyone help me im getting some kind of error it says : Uncaught syntaxserror : unexpected token return and im sure that the mod is causing the error because when i disable the mod i dont get the error anymore
Can you correct this bug ? 
This mod is very good and i can’t active this one
