Hi Steve!

I represent a small group of Ukrainian game developers. We are currently working on some new games and we want you to be their publisher.

Is it possible, that I will send you some screenshots and tell you about games, and you tell me do you want to publish them and what we must change (if so) to make them good enough for you?

In other words, do you agree to control all the way we do these games?

Best wishes,
Kostya

For specific questions about Dexterity publishing, just email developer@dexterity.com. But to answer your question, we won't even look at a game unless it's at least in beta. For a more detailed answer to your question, see this page in our Developer FAQ:
