I don`t play very often siege scenarios `cause most of them are not that good and some of them are really unpleasant (in defence mode you became a spectator and in atacking mode most castles are quite imposible to conquer)..
But this map is diferent .. if you play to defend yourself the scenario keeps you in motion doesn`t let you to only watch but you also have to make decisions in order to win the batle .. In atacking stage the castle can be conquered with a little bit of inovation (i won`t tell u how :-) ) .. So this map it`s fun but most important for a siege scenario is playble.
The map design is good (above avarege) and the castle is very well placed in the ambiance.
To the designer - i think siege equipement will speed up the game a little bit and it with make it more fun.
Really good map .. You should check it out
