Julien Lange is a 30-year-old IT expert in Software Engineering. He started to develop on Amstrad CPC464 with the BASIC language when he was 7. He learned later Visual Basic 3/4, then VB.NET, and C#. For several years, until the end of his study, he developed and maintained several PHP and ASP.NET e-business websites. After his graduation he continued to learn more and more about software like Architecture and Project management, always acquiring new skills.

Julien was at work talking with a colleague in August 2009 and after discovering the high potential of iPhone games and softwares he decided to find an improved game engine allowing him to concentrate only on the main purpose of the game—developing a game and not a game engine. After trying two other game engines, his choice was Unity3D thanks to its compatibility with C# and its high frame rate performance on iPhone. In addition to his main work, he opened iXGaminG.com as a self-employed business in December 2010. This small studio specialized in advergaming and casual gaming using Unity3D.

Clifford Peters is currently a college student pursuing a degree in Computer Science. He enjoys programing and has been doing so for the past 4 years. He enjoys using Unity and hopes to use it more in the future.

Clifford has also helped to review these books; Unity Game Development Essentials, Unity 3D Game Development by Example Beginner's Guide, and Unity 3D Game Development Hotshot.
