Playability: There were several factors that helped the playability, such as the abundant resources, generous starting goods and buildings, and no time limit. But ultimately, after 20 game years I chose to give up rather than hunt down the last surviving wolf that didn't take the bait (see also Balance).
Balance: There were a lot of goals, and while they were very high even at Normal, they were almost all achievable. The 'eradicate all wolves' one was certainly a challenge - I've never seen so many wolves on a map - 150 at least! What was unique was having them fenced off from the castle, and without access to the keep. It kind of made it seem like shooting ducks in a barrel. I'd caution anyone playing this map to think about your wolf-eradicating strategy very carefully before implementing it! I had to restart the game after I made one bad choice which resulted in the wolves overrunning the keep. I think fewer wolves would have made a more balanced map. The second time through I spent a lot of time going back and directing the archers to shoot the wolves, before ultimately hitting upon a strategy to draw the wolves to one spot. Also, on balance - some of the goals were set very high, such as 500 iron, 100 ale, etc., and that was on Normal. A story to accompany the goals would give them a reason for being, and make them seem less arbitrary. There was a good balance of good and bad events scripted throughout, although they didn't start for some time.
Creativity: The layout of the castle was very interesting. I liked how it was in sections on two hills, and I enjoyed watching the people go up and down the stairs and around the hills, etc. The whole 'fencing off the wild animals' was different, and I had fun solving the problem of how to get at the wolves.
Map Design: Overall I liked the map, and the layout of the buildings and land. The resources could have been spread out a bit more to make them seem more natural. There were also resources that weren't needed for achieving any of the goals, but that's perfectly ok - nature is like that too! You might try using smaller brushes on some of the terrain, such as the river.
Story/Instructions: It could have used more than one sentence in the game instructions. Not that instructions were really necessary for the game play, but a scenario could have been constructed to explain the need for the huge amounts of iron and gold that are to be amassed. Also, a minimap would raise the score!
Thanks for a fun map! A few changes in the goals and perhaps a few less wild animals would make it even better!
