Playability 5 : Is simply excellent. I played it 3. First as defender at hard, second as attacker at hard (failure), thrid as attacker at normal. As defender is a bit frantic, because you not too much men, that make you often anxious... even it's only a feeling. As attacker the castle is tricky, especially to find your way to the keep. And damned killing pits and pitch. But I enjoyed this map.
Balance 5 : Very well balanced imo both as attacker than defender. (perhaps a little too pitch and traps for my feeling)
You have only to find the ideal setting for you. I could perhaps suggest to dont try above normal as attacker, and ignore the lowest setting as defender.
Creativity 5 : well I have to explain, because I feel most will not find this map is very original or creative. First it's an historical castle. Second the story is based on historical events. Thrid, is quit a little castle (at SH siege map standard), with little garrison (about 35 of all kind). And only 8 archers and 5 xbowmen. The author didn't tried to make a superproduction based on historical fact. He give us a map "with an human face". Little garrison for defender. For attacker, I quit sure the was made all it could to be faithfull to what hussites were, even he had to adapt both at stronghold units and balance of the game (you have no engineers). At the end you have a very rare kind of map, perhaps not unique, but at least very rare. It change from map where you have an hollywodian castle with 250 soldiers stormed by 750 invaders.
Map design : 4 a little deception in comparaison of Konopiste (who was perhaps helped to be in a forested region). I sometime feel it's a little fat and empty. But perhaps Hazmburk is located in a flat meadow area? Anyway good design of the castle.
Story instruction 5 : A detailled history of the castle, with some info to events related to it. Once more It's a pity the author didn't post it with the map.
Overall a very good and original map imo.
