Let me tell you a story: AndyAce83 wants to make game. He has an idea. A beat-em-up game based on the trend of bumbfights. He will call the game Bum-Fight the game.
Since he is an avid image creator he creates a cover image for the game and then writes a text on 2 A4 pages about what the idea is about. Since he has played a lot of games of the genera he has also some ideas of what gameplay will be etc.
So when the idea has exited the first stage, he has a confession… He has no bearing on how to make video games. He can now read up on it (talk to you in about 5 years) or hire someone who has more understanding, knowledge and experience, than he. He chooses the latter option.
But the game will not be made because AndyAce83 sucks also in running a business… but atleast he tried.
Now how about you create a beat-em-up game based on the idea to AndyAce83? Then send the game to him and say what gender you and your collaborators have. Write that you give AndyAce83 full right to develop and sell this without you getting something out of it.
