So you want someone else to come up with an idea for you? Bad idea, not many people are likely to want to do that anyway, why wouldnt they just make it themselves? And even if they do its their idea not yours, how can you possibly see the same thing as they imagined? Best you can do is create a clone of an existing game but give it an original spin or do your own planning, it's really the only way to create a good game because you'll have the passion to bring it to life if it's your creation... You can't cheat creativity
