"Constantinople" is actually named "Constantinople 1453 CE" by its original author "PtolemyGonzo" and is another siege battle depicting the famous city which claims to have been designed as a multiplayer scenario first.
Its your fairly normal siege battle with a starting pop cap at 300 already;land your legions of troops and began smashing the city with an elephant horde. You can convert some villagers and go B&D if you need backup at some point;really its just a random map with a big ole city smacked on it, and a billion men in transports waiting to rumble.
The game has a serious balance oversight, which is that the players king, when killed, triggers his own victory. Besides that, for both singleplayer and multiplayer i found it fairly poorly balanced. One thing is that the invaders have no villagers, only a few monks, while the defenders do have access to a full B&D setup as well as their city. The players starting 300 units with dozens of war elephants, mamelukes, bombard cannons and jannisaries are only in the castle age, versus the imperial enemy, and rather lacks the overwhelming power you would expect;nonetheless against the AI its no problem to defeat them, as the AI is utterly crippled by its town center positioning and pop cap. If this actually ever was a multiplayer game as claimed, i would be a little nervous that the byzantines might have an overwhelming long term advantage.
There has been an attempt to make a game that's different from a random map, but its little different from any other siege scenario and it has some wacky events in it. Mostly its just a random map with a huge city and a massive army attacking it.
Map Design 2
It looks like a random map that's been modified for the purposes of the scenario. There is annoying gaia wildlife scattered about. The city itself is a large block of road1 with no decorations and the buildings placed in a grid.
There is some objectives and hints but its fairly thin stuff. Besides that, its all written from the point of view of the defenders;it has the impression of being taken from some other scenario out of context.
