I'm new around here. Love the game. It got me thinking. What about some random elements. Ie: a mine exploding, or a generator catching fire and being detstroyed or offline for x hours same for factories. There may not be a high chance of this happening, but having it happen now and again could make for interesting play. Also should there be a minor randomness to combat. Maybe 5% or so. So that sometimes the under dog may before better etc. also I like the idea of shields going down to an event..
Just something to consider
