A relatively simple concept that would quite easily further the distinction between empires and kingdoms: while "beast dens" such as wolf lairs would create obstacles for Kingdom players as you might imagine, give Empires the option (perhaps with the necessary research) to use these landmarks as resources instead, allowing for the opportunity to create trained war beasts.
Benefits of such a change would include:
- greatly improved distinction between empire and kingdom armies on the tactical field
- unique research opportunities for empires
- map-based play-style and strategy differences for empire players vs kingdom players
What do you guys think?
