It was okay, the city was already up and running when you came along, but there were some integral elements of a city missing. (woodcutters) I found I was unable to make crossbowmen which left me unable to deal with the swordsmen that came along, and I couldn't make enough swordsmen or knights to fight off the numbers.
I couldn't make enough soldiers. The units I had were mowed by the amount of swordsmen that came and I couldn't use classic defense strategies because the stone pathways stopped me from making a gatehouse. If the attacks came from the bottom signpost, you were scrooed.
Patways were a cool idea that was executed poorly. If you had left room to make gatehouses I could have survived the assaults. The rest of the place looked okay, but btw aqueducts bring water from a high place (i.e. mountain) down to a low one. They didn't magically have the water flow up from a river.
Map Design: 3
Few pieces of eye candy, wasn't enough to cover up the massive boring places all over the top half of the map. The iron was just there like "a slap on the back" and there wasnt enough texturing on the map overall
Story was sort of boring. You shouldn't have listed what was coming, I knew exactly what to prepare for. Add some mystery into the story.
Work on making your maps look better, and playtest your maps a few times before you submit them.
