Interest in so-called scripting languages within the Games Development Industry has grown in recent years. Now it is common to expect even games ‘designers’ to have some experience with such languages in order to prototype and demonstrate gameplay features. The aim of this project is to investigate two of the most commonly used scripting languages: Python and Lua. It will seek to establish typical uses of these languages within Games Development and will compare and contrast the facilities within each language for such applications. This project has its own aims and adjectives. The main aim of the project will be investigating on the Languages used for game development considering mainly LUA and Python and to understand flaws and plus points of both. My investigation will also look forward to conclude which language is best suitable and more efficient. Python was into the games development industry for a very long time before LUA was been introduced, and is still been used a lot, and then came the LUA and become quite popular, if so then what was the reason behind this?
