HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

I didn't notice that it was a small map; there shouldn't be any sawmill guards on it. As for the 10+ (at least 16) wood resources per Hive on a small map, it's possible, but only if the wood resources are upgraded (as they were), there's nothing else near the Hive, and you get a little lucky. Regarding Storms and Monks, on a 6000-point small map with strong monsters, there are 15-23 of each.
