Is crowdsourcing an idea for a game a good idea? I like the idea of getting advice from more experienced people, but it also makes me nervous. I'm also curious if crowdsourcing can help to sell the idea to others. 

Everyone has opinions. Not all of them are valuable. Getting advice is useful. But nobody 'buys' ideas.

That's a fair point. I meant selling ideas, as in convincing people of the viability of the idea, rather than for profit, but it is still good to know that I won't make money off of an idea alone. Thank you again!
