Hey Nook. I've spent the last month creating this map on and off, backporting in updates as you've released them and I'm very pleased with the result.
Since finishing I've drafted a design document to use the map to play a sort of card-driven board game. a game within a game sort of thing, itself based upon mappa imperium's rules. The idea is still in its infancy but I'll let you know if anything ever comes of it.
Thank you for all your hard work making mappa imperium, it's scratched my civilization building/observing itch in a way very few other games ever have.
