File extension GMV description:
The CyberBoard board gaming system makes playing board games by mail and electronic mail a more enjoyable experience. The system allows you to easily graphically design the various parts of a board game on your computer. The players can make their moves and exchange recorded versions of the moves with their opponents. The opponent can then play back the moves. Although many types of games may be created using CyberBoard, games that use counters or chits such as war games work particularly well.
