Ideas are mostly worthless

“What you think is a great idea, almost certainly isn’t and likely has been thought of a hundred times and more. Ideas don’t sell, GAMES sell – no one will buy your idea. No one will make your game for you – they want to make THEIR games. Most game players think they have ideas for good games. But few ever complete a game design.

And

“The idea is like your finger, we all have them, but the implementation is like your fingerprint, everyone’s is unique.”
