Playability: 4/5. This is a smoothly made, good quality map. I found it plays better if attacking and should give you a good fight. A tricky castle to siege too, with distinct entrances, all with their own advantages/disadvantages. Good use of pitch ditches and killing pits adds to the playability, and longevity, of this.
Balance: 3/5. As above, I initially played as an attacker on normal setting, and suffered horrendous losses, but won on first attempt and 96% troop loss (I know, I know). PLayed as a defender, which is how the map opens and therefore how the map should be played (?), I found it too easy. Still, it's well thought out and I thoroughly enjoyed attacking this map on normal and would certainly play this again and again.
Creativity: 3/5. An average score. Whilst there's nothing wrong with this map, it lacks something overall, probably a story or historical intro to the castle.
Map Design: 4/5. The landscape is quite well done, good use of scale and would benefit from a little more rendering to smooth out some of those edges. It's still a very good landscape. But the castle itself is excellent. Looking at the walling, the towers and the site overall it's a commendable reconstruction and it's easy to see that the author has taken time to try to recreate a castle accurately. Very good work.
Story/Instructions: 2/5. The only bad point about this map... no story. Nothing to introduce you when reading the description page and a few lines before the game launches after downloading. This is a great shame, because there are people out there that would love to read in a bit more depth about castle history (me included).
IN SUMMARY: Take out the fact that there's no story and you are left with a great siege map that shows promise as a download to keep on the hard drive for a long time to come! Full credit to the author overall, for a very well designed map.
