I don't know how they do it?!?!

A game or your game? You are saying $30 elsewhere in the post.

Volume. Efficiency. This may help:

As little as 3% of each $1.50.

That is factored into your Costs of Production. If you produce multiple products and recycle some artwork then you reduce the CoP on future releases. Hopefully, you've been paying the pittance that most startups pay for freelance artwork, and then larger firms have salaried staffers. I've seen at least one $20 RPG book that was half recycled art from the company's archive and half public domain, and you can get some pretty decent stuff on Fiverr with commercial rights for $50 and under.

The profits are proportionately spread across the field. There just isn't much money involved. Yes, the designer literally gets pennies on the dollar. I don't think there is a single reliable source that remotely suggests otherwise. But I think all of this has been covered ad nauseam in previous forum posts.

That is kind of the point of kicking your tires -- not to make you lose confidence, but so that you'll get over yourself enough to go back and review the fundamentals. I am happy to see that you are reviewing the margins and determining what risks you are realistically prepared to tackle, because frankly, I've been worried that you are hemorrhaging money on your game and that your unrefined business plan was going to leave you a lot out of pocket with nothing to show for it except disenfranchisement. When you say "another investment of +$10,000," I tense up, imagining a garage full of dusty Quest CCG boxes, because if you had the distribution channels nailed down and everything sorted from that enterprise then we wouldn't be here right now.

More than anything, you need to decide whether you are a game designer or a publisher. As a designer, get this thing off your hands. Sell it, and then you are done with it. My principal concern here is that you may have over-invested in your product. I've lined up and collaborated with artists before, but the publisher was always the one who reimbursed them. Depending on what you paid, it is possible that a publisher won't be able to cover your costs, leaving you out of pocket with a 5% royalty check on future sales. Hopefully, you negotiated some great terms on all of the work you had done, which is normally the domain of the publisher. However, I get the impression from your posts that the Game Crafter sales haven't offset your investment.

If you are a game publisher, and actually enjoy the ulcer that entails, then it is time to set the designer hat aside and consider the game pro-bono work. You need to work on scaling back your funding goal with realistic solutions to get your cost of production down to a manageable level. You need to figure out your distribution system, your target market, all sorts of factors. Keep in mind, when someone does a search for your game, these forum posts show up, and so they need to start reflecting forward progress, increasing confidence, and an adaptive approach. They can't all be "WHHHHHHYYYYYYYY!?!?!?!" There have been some good suggestions so far here, and I think you generate enough responses to get useful feedback to this end if you are really looking for it. If you were in the U.S., I would direct you to an organization like SCORE, but I don't know what the Canadian equivalent is.

Keep in mind that the great thing about Kickstarter is that the backers take the gamble, not you. That's why it exists, so that designers don't bankrupt themselves investing in a product with no market. Added to that, even accounting for KS fees and so forth, it is a direct sale that is rarely discounted as much as you'd give a retailer. You probably won't make much money even then, but if you want to build the foundation for a business, or even a reputation as an individual, then this is a place to start. It seems to me like you already have one foot in this pool, but you've been hesitant to take the plunge.

Really though, what is your ultimate goal with this game? And you only get to pick one.

Another thing to mention is that publishers are dealing with larger print runs compared to what you can afford in self-publishing. That changes manufacturer's quote considerably. Between 1K print run and 3K print run there can be 50% price difference.
