Thanks for he info, yea I pictured tunneling as the most intensive part. I had a few ideas of creating separate cells for the nests, but I would also settle for inhabiting a cave or old fortresses and things along those lines. I pictured you starting as a queen such as in the old Sim Ant, after picking your species (hopefully flying will be implemented by this time) you will find a suitable location to start your nest. Each queen will be fitted with stats appropriate to its species, and maybe after clearing a cave,dungeon,etc, you can settle in and start laying eggs. (Still need a mechanic for that also) You become the first born and start gathering food for the nest (wild animals, tamed animals, maybe even the citizens of Skyrim) and carrying on the basic activities as in the simulator. There would have to be a basic UI for each species, but thats for another post.
