Two Questions and a Suggestion....
Question 2) When you search for someone you can see their home base. Is it possible to see sub bases, oasis, or Fortified points?
And finally, a suggestion if the creaters ever look at this. How about a "Navel Port"
You can then have ships as a unit, you can "fish" to gain food (then just combine grain and fish into a resource named "food") you could then capture say oil points, to fuel the ships. I'm sure there is more you can expand from this aspect as well....
Thanks for the time.
