I have contacted two publishers. They're really slow to get back to me, and I don't really know what's appropriate in terms of asking them for status updates. I sent inquiries out on the 29th of February. On the 16th of March, one person told me she'd be pitching it at her next meeting, tho she didn't know when that would be.
The other was a friend of a friend who works in a publishing house not too far from where I live (they have published tarot decks in the past). She's not in the arena of accepting new projects, but she wrote me and told me she handed it off to the person who is. Since then, I haven't heard back.
As far as I can tell, publishers have lots of people contact them and a very "don't call us we'll call you" attitude. I'm unsure whether I'm "allowed" to contact other publishers or what. I find it intimidating. At this rate, tho, it could take years just to find a publisher. That doesn't seem fair.
And I agree, perhaps my fear they would take over my work is irrational, but I do want to retain rights to the images. I also agree that most ANYone has better marketing skills than I do
Based on my experience in other areas of publishing, I'd give them another two weeks and then get back in touch. They may be passing it around within the organization, and that takes time. I don't imagine there's a prohibition on multiple submissions--it's not academia. The US Games guidelines don't say anything about it. Good luck!
