Nice one! XD
It's true. Game companies just plain aren't interested in anyone's ideas. They have teams of people that they pay to come up with ideas for them, and even then only a very small fraction of those ideas ever get used.
There are two ways to get a video game company to listen to you:
1. Go to work for them. You have to start at the bottom doing shitty grunt-work for several years. And they don't listen to grunts. Grunts are there to make assets and program the ideas that the company already has. If you're really, really excellent (as in better than all of the hundreds of other people you work with) then maybe you can eventually work your way up to a position where they will start listening to you. And even then, AAA titles aren't designed by one person... if they like your idea at all then it will be passed to a committee where all of the details are going to get changed in order to make it more marketable, and your idea will no longer be your idea anyway. Also, they get all the rights to it.
2. Make your own hit game that makes a shitload of money. Money talks. When they see the giant pile of money that you made with your game, then a big name studio might be a little more likely to listen to you. But even then your game is going to get passed to a committee where all of your ideas get changed.
Basically the only people who are allowed to make a game exactly the way they want to are indies, and they have to do it on their own.
At any rate, 99% of being a solo game designer is trying to keep yourself from getting too epic. You have to learn to work within your means or else you will never make a game. My advice is to take your best 2 or 3 ideas from your epic game and throw the rest away, and make a smaller game with that.
