An interesting scenario with clever ideas (must not spoil them).
There are no eco requests, the aim is to survive several invasions. But the mission is eco-centrered by significant restrictions of buildings, of trading (only pitch), and of units.
Due to the small map, hunting deer is very effective.
A hint: Take care for the stock of trees. On earth & sand, only olive trees respawn; palms need greenery.
The invasions vary which is exciting. Again, the small size of the map has effects. You cannot build defences everywhere you might like. On the other side, the sign post is too close nearby and in range of the marksmen. Two signposts would have been better.
Found the mission some years too long and thus unfortunately too easy. Collected thousands of gold and trained 310 archers.
