I don't actually own this game. Every few months or so I search through boardgamegeek.com for cool maps. Anyway, here are some reasons to like this map:
- The hexes are numbered, which is the key to stocking a wilderness sandbox.
- Look at all those opportunities for seagoing adventure!
- Check out those light blue land hexes with the squat buildings on them. The key says the magic item chits start there. Those are the most famous dungeons/ruins in the realm.
- Roc's nets are marked on the map! That's fantastic! That's an instant hook for the campaign world right there: everyone lives in the shadows of these giant flying predators. In Basic/Expert D&D rocs grow up to 36 hit dice in size, way bigger than most monsters. Even dragons skulk about when B/X rocs are on the hunt.
