A great deal for variation & atmosphere would be guard entities with their looks fitting to their terrain location. For example, make this the guard entity for desert biomes: http://www.planetminecraft.com/skin/sultan-saladin-3285815/
and something like this for winter biomes: http://www.minecraftskins.com/skin/10575513/winter-soldier/
etc. (and equip some guards with bow & arrows, so they can defend from the towers)

I like this idea, however I can't tell if it would be OK to use those skins in our mod. If someone was interested in drawing some new skins (and wouldn't mind some possible final edits from the ToroCraft team) I would write the code to use the them. We could switch them based on biome, or maybe make it depended on what civ they are affiliated with.

yeah i understand, for clarification, i merely did a quick search for the skins to make a proof of concept, my intend was not to rip the skins from the sites without crediting the authors. I could try to contact some skins makers to maybe get their permissions however, or i could try to make them myself, but that could take a while...., we will find a way :D

Thanks for taking my idea into consideration =)
