Pitching Video Game Ideas

I have a radical new idea for a video game – who do I contact??

This idea has never made it as a game before and I would like to pitch it to various game producers so what do I do??

Find the game producer’s website with their email and ask if they are interested in any game ideas at the moment.
And try to be polite, they don’t like people who say, “Here, this is my idea, now make it or I’ll never purchase anything you make and rate everything you come out with badly.”
