There are no town centers, buildings, or even neutral settlements and villagers to start with on this scenario for both players and therefore limited to only your starting units which are an army of heroes for player 1 and a single unit for player 2 which is hidden behind a dense forest. Both players also get zero resources. Player 1's patron god is Zeus even though its about recovering the land using over 1000 uses of Gaia's god power, Gaias Forest, and Odin's god power which is the Great Hunt to clone the scarce animals which are basically just randomly placed around the map.
Player 1 gets almost the entire entourage of the heroes from the Fall of the Trident campaign plus some vanilla mortal heroes while player 2 only gets a single anubite. Both players are considered neutral against each other, and if player 1 decides to set player 2 as enemy and then attempt to destroy him, it would be almost impossible to do because player 1's unit can't reach or even see player 2's anubite which is hidden behind a dense cluster of oak trees on top of a hill. The only way to eliminate said anubite is to use a cheat, add a flying unit or trigger on the editor to reveal the map and remove the fog and then casting bolt on the anubite.
This scenario does bring a nice, if obvious, message about environmentalism and animal conservation, and I've never seen any other scenario like this where you grow trees and clone animals and such. I could be improved upon by making the message more subtle and adding some trigger tricks.
Map Design: 1
The design of the map is just terrible. The northern part of the map is a Norse lake filled with outrageous numbers of Salmon fish surrounded by Snowy pine trees and a few walruses which contrasts with the surrounding barren land. The Hades terrain used to represent barren land is the unbuildable type which means you can't place buildings on them if you have villagers and resources (the buildable type ones are located in the 'Scenario' category). The east, west, and southern part of the map is filled with dense oak trees that somehow are unaffected too. The scarce animals are basically placed one-by-one randomly across the map. Terrain mixing (mixing an area with several types of similar and related terrain), Eyecandy (making unique, appealing spectacles out of AoM objects), and some embellishments will definitely improve this category. Reading the scenario designing tutorial or even copy and paste them into a document and memorizing them in case of Internet problems would help.
Other than "recover the land", the only true way to win this scenario is to kill all of player 2's units (see Balance section for details). I know this because I checked the triggers on the map editor after i was confused by what to do next after i filled the barren land with trees and animals. Also, why is the land barren in the first place? Maybe it's because someone invented nuclear weapons or such?
Additional Comments: Don't be discouraged by my review. I myself isn't that good of scenario designer either, and just because this review is more than a year late doesn't mean it shouldn't have any influence whatsoever, although I do fear that the author of this scenario is no longer active on AoM Heaven...
