Hi Linda, thanks for your question. First up, yes, if we work with you, we can sign an NDA by negotiation. We often do. But when you say you have a version of a "familiar" game, do you mean a game someone else has already invented and produced? Because if that is the case, you may risk breaching copyright and plagiarism laws even if you've made significant changes to the original. We would suggest you take legal adivice on that front. And if the game was too close to something already out there (crudely called "a rip off"), we would not be able to print it for you. Just to be transparent with you! In any case, we've asked one of our experts to contact you via email, so check your inbox and spam/junk folders for that.
