It was definitely influenced by roll-and-writes and flip-and-writes in general but I hadn't seen Cartographers when I first released it, I think Cartographers may have come out the same year. I recently got a copy to compare, but haven't got round to playing it yet. Glad you enjoyed it.
Oh yes, I saw that it was the same year - so I doubted myself after I wrote that.
Since you haven't gotten around to it yet - my one recommendation for Cartographers is to play with coloured pencils to fill in the spaces. 100% a better scoring and gameplay experience in my books.
