“Best map for Heroes of Might and Magic III” (2007).

RUH-CHUDISHCHE-OGR, VoG maps are not accepted by the contest rules. Use this program to convert your map to SoD format. If that doesn't work, I think you'll have plenty of time to make a map specifically for the contest, or adapt another one of yours (if you have any). In SoD, it is also possible to create great maps for a Walkthrough.
