My 2nd submit
1. Frederick mega fortress
2. Richard's big square castle (Jalan ruet gang buntet)
3. Saladin's TV Antennae fortress
added:
4. Wazir's Ar-Ra'd(thunder) fortress
For me Saladin aiv looks same as firefly created aiv's... maybe only
new thing was antena :D And brewerys build a little too close to
stockpile. That cost for saladin a little bit :)
Frederic aiv is not tested as i saw in aiv editor... Becouse church
was blocked by water and wall... And it only would be really bad for Frederics economy. Maybe that hexagon is something new in Frederick aiv colection. And there are more of weapon producers. But for Frederick in every castle better to build more then 2 armorys... best is 3... becouse then he sells weapons when limit is reached :)
Richards aiv... And that one long walk like in labyrinth is bad for Richards economy it would be better if you placed another gate house in bottom of castle :)
And stairs... Your idea that ally would dig him a moat becouse you
have added some water around his main keep. And he is not digging for him self a moat... its only way to see that Richard have a moat a round his main keep wall.
Please, before submiting a aiv's be sure that they are full in action :)
