I've just come across an online map generator which looks as though it has huge possibilities,
particularly for campaigns:
https://azgaar.github.io/Fantasy-Map-Generator/Opening the site generates a new map (which can be saved once it produces something you
like). Click on the 'little brown arrow' to access full features. Each map is complete with
numerous layers (political, military etc) with most of the features fully editable. The map also
comes with pre-named States and deployed military units / fleets which can then be customised
& moved into action. The latest version includes a feature to resolve battles.
Best of all, it's free !
Well worth a look. Made me wonder whether anyone else has previously used this generator
and what they thought ?
Cheers, Phil
