Quote:What makes it so easy to use?

A combination of a "batteries included" API and easy-to-read code. Things like forced indentation really help, in my opinion, and everything is always easy to use. Reflective code? one function call away. File IO? One function call away. Databases? Import the built-in module sqlite. I find it more useful than other programming languages in most of what I do, though there are always reasons not to use it, depending on the situation.

Quote:Why dont more people use if its so good?

I'd say that "old habits die hard". That aside, Google uses it, which is major in itself, as did Civilization IV on the game side of things. In fact, Python is the 7th most popular language according to TIOBE's TPCI.

Quote:What major diffrences would make someone choose C++ over Python?

Speed and flexibity are Python's field. When I say "speed", I mean speed of writing, not execution. C++ is useful for all things that need runtime speed, but Python is useful where you need to be able to change your code easily, run it across different platforms, or simply make a quick solution to a small problem. So when somebody chooses C++ over Python, they want it for something like a physics engine, or a major number-crunching program.

Quote:Is python capable of making a game much like Illusions of Gaia?

I see no reason why not.

Quote:What sorts of things in python not make people want to use it as there dominant programming language.

Some people simply don't like Python, and that's always the case for programming languages. Other people have no need for it, and all of their code is for speed of execution.
