Unpolished Creations is primarily a place where Nathan Skoczylas posts his game development work; acting as a portfolio. The work done is usually in Unity3D using C#; however, some projects will use C with the OpenGL library.
Additionally, instead of just being a portfolio, Unpolished Creations is a place where [game] developers can go to get source code on projects Nathan has completed. The source code provided is open for anyone to use in their own games; furthermore, one may even expand upon the existing projects to implement new concepts and ideas (Feel free to post a link to your project if you have used the source code from one of the projects!).
