We have done 100 times more than we originally planned and we have ever dreamed of.

That was indeed a ton of a good work! It's great to hear that it was satisfying for you as well and not only a yet another product to mantain. Keep on! Can't wait to see what the next year brings! How about re-claiming burnt planets for i.e. 3x stardust gained from burning them? :) You know, terraforming and revitalizing costs a lot!
