The official is because people at Atlas Games will know about it and help in it's divulgation (https://forum.atlas-games.com/t/catnip-garlic/129/1)... And those maps will have only material with references in the AM books...
denubisx, can you please post the links of your maps here?
For now i just put the link for one map, but a friend of mine is working a lot too... so soon a will post more links...
Other thing is to help to make the maps better... Most people complain about the same thing: a lot of guessing and that the distances of cities and villages in books don't match in google maps... So i think a good discussion of those locations would be healthy =P
For the locations cited in the 5ed books, we can try to talk with the autors, but what with the older editions?
ideas, ideas, ideas =P
