Unfortunately, we had a lot of problems with the client/server maps syncronization, so in the last few days we had to spend a considerable amount of time fixing those issues. When something was fixed, another problem occured. For the time being, it appears that client and server syncronize the maps properly. But there are a few things we didn't test yet, so there might be problems in the future.
A nice thign about Barren Moon, which Eternal Lands does not have is that the monsters will actually be intelligent, and 'alive'. they will not just wonder around aimlesly, and attack players, but they will also look for food (each monster has a table with the objects and animal types it eats), shit (to enrich the soil), and try to avoid the enemies (which are defiend per monster). So if a rabbit sees an wolf, it will try to run away, while the wolf, if hungy, will try to eat the rabbit.
Furthermore, some animals will respawn when they die (the wild animals) while the domesticated animals will NOT respawn when they die, but they will reproduce under the right circumstances.
So slaugheting all the cows in a city will be a bad idea, at least two cows should be left so they reproduce.
The harvesting system is much different from Eternal Lands, so the resources are limited. That is, there is only so much you can harvest from a plant, for example. In addition, some resources will slowly regenerate, even if they are depelated. But the regeneration will be slow, much like the gas in Starcraft.
Since the harvesting system is different, I had some problems addapting the Eternal Lands system to the Barren Moon one, and last night I had to spend hours debugging stuff. Right now it works as expected, but it is not totally finished yet.
