I am not familiar with what C# can do, especially in the context of a Xbox 360 game, but is it possible to execute Python scripts from within an Xbox 360 Indie game?
I've read several times that you'd want to write the game graphics and logic in a quicker language like C#, and then use Python as a scripting language for fast iteration. Is this sort of thing possible for development on the Xbox 360 platform?
Well although C++ is the language of choice for gaming industry, I have seen really good games written in C# using the XNA framework. In terms of your scripting question, I believe Blizzard uses Lua for UI in games like WoW. But going back to your question it's possible to have Python integrated to C#, there is an open-source implementation of the Python programming language which is tightly integrated with the .NET Framework called IronPython.
