Overall I like the changes in this version. And even more with the ones coming in 3708.
I want a super Z-power-gen.
In one of my games I now have -2 million net energy, while producing 1.7m. Fortunately I am currently not under attack.
Too tired to enter it into the bugtracker, but it would be a good idea to have the game start paused after loading, so you can get an overview of the situation.
