Roleplaying Tips

Hi John
Loved your recent article in RPT #688 on Map building via a deck of cards;
I have tried it out once, but then realised most overland / large scale mapping is done on a hex based grid.
How would you convert the layout to a hex grid?
Glad you enjoyed the article Malcolm, there will be more kingdom building articles coming out over the next few months 🙂
To answer your question I would suggest assigning each card a number of hexes on your overland map (depending on how densely you wish to populate it) and then, once you’ve turned over your cards, you can choose a hex within that area to locate the settlement/adventure site.
