Nobody is going to give you money though unless you have a tangible business plan or documented examples of your ideas. i.e. concept art, playable demo or mod of an existing engine, extensive design documents. Plenty of people can come up with good game ideas, the trick is to mold that into an actual workable idea and that that all down on paper or in a playable state. Having something that people can actually play, even just a simple demo, can go a long way in convincing people you can make a FUN game.
