There's a common belief in some communities (e.g., here) that game ideas are worthless. The thought being that everyone has lots of ideas, so why would anyone choose to make someone else's idea over their own. I think this might be wrong (or at least a dangerous mind-set to get into). Here's three reasons.
- See lostgarden's game prototype challenges. Danc posts a game design and some artwork, and other people make the game. Now, you could argue that they're only valuable because of the inclusion of artwork; you could argue that the ideas themselves are still worthless. I disagree. For one thing, artwork is typically only valuable in a very restricted context -- if danc posted some artwork without any game design, I think a lot of people would download it (danc is a good artist), but I honestly doubt that many would end up using it. Without the idea, the artwork loses a lot of its value: The idea is valuable too.
- Ideas range from large to small. Often people come up with large or at least medium-sized ideas. They can usually be broken down into many elements, and looked at from many different angles. It's also usually possible to take these elements and combine them with other elements from completely different ideas. Maybe if you share a game idea no one will make that game, but perhaps someone will find some aspect of the design useful, either in itself, or as a seed for some other idea.
- "Creativity is hard". I think this is also a fairly common belief (actually, I think there's a strong bi-modal distribution -- there are people who think creativity is really easy and people who think it's really hard, but I think the number of people who think it's really hard is definitely significant, and probably the majority). Indeed, there are often posts lamenting the lack of creativity in modern game design (although that's a large and complex discussion in itself, so it certainly can't be pinned down as being just because "creativity is hard"). But surely "creativity is hard" and "ideas are worthless" are contradictory statements -- if creativity is hard, then being creative must have worth.
