Talking about wolves. We jumped on the idea of more intelligent creeps, and one idea we came up with was this –Wolves hunting farm animals!
Human economy includes herding animals such as pigs, sheep and cows. And these animals generate more resources and fatten faster in they are herded some distance away from the city. We can create AI for groups of Wolves to come after such herds once in a while. Of-course, there is an issue how same wolves can harass other races, and how can we keep this from getting annoying/redundant, or too random to offset balance. *sigh*
We are still working on it, you guys have more ideas?
