Through the history of the game, resources have been added or modified whenever new features have been implemented. Well that time has come again, so I feel you should perhaps modify some of the existing resources (my suggestoin furs and lead, and whatever else you see fit) to better equip the new feature. Along with this, perhaps a new improvement, or improvement modifications, such as intellgience agencies and satellites providing better spy chances etc. Additions like these I feel are imperative, and I am sure others feel this way as well, especially those 'tortured souls' who were cursed with fur ( )
At the very least it would stop some complaining and add a little more strategy to the game.
