Can you tell us more about the scale of the map, especially the amount of time covered by one game? For instance, could seasons play a role?
Other than that I know that a dynamic weather system would increase the immersivity (is that actually a word) for me hugely.
And I guess 10 species would be a bit sparse for creating a believable foodchain etc.
Just some random thoughts. :)

hawkerhurricane Regular ShmoeFor my current project, I'd like to create a rudimentary ecosystem on the island on which the map takes place. I feel as if this would contribute to gameplay immersivity, as well as make for an overall more enjoyable and realistic map. I posted this in general, as I was not sure if it was a "data" or "trigger" matter or a mixture of both, and I didn't want to make redundant threads.
I assume this is in fact possible(it may not be). The features I would like are:
-Mating; with production of offspring
-Feeding[Herbivores feed on certain varieties of plants; Carnivores feed on specified animals lower on the food chain]
-Drinking water
-Sleeping
-Roaming/Herding behaviour[certain animals form herds, animals roam across the island]
-Fleeing/stalking behaviour
-Territorial behaviour[Certain animals attack others their territory is entered]
Number of distinct species is between 10-15[is this too much?]
Thanks for any and all help in this undertaking. I'm not starting this part of the map now, but I just wanted to be aware of what is required before I begin.
