title: Game Development in Python, ruby or LUA?
body: <p>I have experience in game development in some game engines in Action Script 3 and C++.
  However, I would like to improve the productivity and so I want to develop a new project in Python, ruby or LUA.
  Would it be a good idea? If yes, which one would you suggest? and what is the killer game development tool set or engine?</p>
