Fastlane is offering really solid advice.

I only have a few things to add.

1) Raising Capital is not an "Art" it is a "Science". You will need factual evidence that you will be able to produce a product using the funds. You will also need to supply solid histroical evidence that your game will sell x number of copies.

2) Think past just raising the funds. How are you going to pay that money back and what is the acceptable return for the investor. They are thinking in dollars, you need to also.

It's really not about the game it's about the money. If you can not demostrate that concpet to the person you are asking money from, you will have a hard time getting the funds.
