Since 1997 or 98 i've developed a number of free digital maps intended for use with generic hex-and-counter war games. Those maps used to be hosted here, but they are now hosted over on Google (no Google account is needed to access them):
- Most of the PNG/JPG-format maps are in this public Google Photos album. Subscribing to that album will allow you to receive notifications from Google as that happens (subscription requires a Google account). Subscribing is not necessary to view or download the images, only to get notifications as images are added to it.
- The maps, including any SVG- or GIMP-format master copies, are hosted in this public Google Drive folder.
All of those maps are, unless noted otherwise in their comments (see the "Information" tab in Google Photos), released into the public domain, free for any purpose. The small handful which are not public domain are free for non-commercial use.
