 - This is based on a list from [GameMaker Libraries](https://github.com/FaultyFunctions/GameMakerLibraries) and from Gleb Tsereteli with additional links/details.
 - A majority of linked resources will only work with `GameMaker 2.3+` due to GML syntax changes. However, if you are working in GameMaker 1.4, most library creators would appreciate it if someone makes a backport of their project. 🙂
