Quite regularly we get submitted a design document or prototype of some game or software idea or web concept from some ambitious young person. The proposal is usually quite vague but they insist it's a revolutionary idea that, once made, will make millions of dollars.
They are quite..generous as well in their proposal offering to split the proceeds that their revolutionary product would make 50/50. Others generously offer to sell us the concept for a reasonable cost. "All" we have to do is make the program and presumably wait for the money to roll in.
Ah if it only it were that easy. In the real world, ideas are cheap. In fact, I'd almost say ideas are worthless in themselves. Most people have neat ideas for products, services, whatever that they believe will make big bucks if they could get it made. But that's the thing, making something is worth a lot more than the idea.
Making a successful product or service is really a multi-step project:
1st: You have the idea. That's the easy part.
2nd: You have to then develop the idea. If it's a game, or other piece of software that means you have to probably pay software developers to actually make the thing or if you're a programmer yourself taking the time to make the thing in such a way that people would want to use.
3rd: You have to put together a way to distribute your product or service. That's a lot of work too.
4th: You have to then spread the word about your product or service. I.e. you have to put together the marketing. This is a whole different discipline that involves a lot of hard, tedious work.
Usually, people in a position to actually do step 2 have lots of ideas they'd like to do themselves. So when some guy sends me vague game design about doing "realistic surgery" offering to pay us a 50% royalty for each copy sold (after we make the game, then get it into distribution and handle the market) the answer is always "thanks but no thanks". We have lots of ideas too.
So if you have some revolutionary idea, your best bet is to find a way to make your idea come true yourself. Because it's not the idea that matters, it's the follow-through.
