Playability: A 4 because you have to think you don't start out with a lot of resources and you have to get your food production up and running (not to mention your industry).
Balance: A 3 Because any army you set to invade can be stoped if you get a lot of archers to the walls but still you can in crease the numbers to imposible and your walls in the map will make it possible to beat.
Creativity: A 4 because i have never come across a map that has a handicap in that fashion, also the unquite thing in the map is that both the iron and stone sites are in the confines of the castle.
Map Design: A 3 because the map itself does not have that much eye candy, but the map has alot of defensive benefits, the sign post is situated in a penensula and you can funnel them into a killing field by either useing walls you guide them to the main fortress, or building a wall from shore to shore add gatehouse and towers (preferablely round towers) and stuff them with archers and crossbowmen.
Story/Instructions: A 1 because unfortunatly there is no Story or Instructions (well there should be no instructions because it's a freebuild) all it saies is the title of the map so a 1.
Overall a 3.5 if you count out the 1, It's a good map but it could still has some room for betterment, but a good example for use as a template to build another map.
