What would the construction cost of the Energy Collector be? If it was cheap enough, it would be an automatic build on all new planets. A settings option to "Automatically build Energy Collector near Command Station" would be really nice. (unless this seems too much like modules). Alternatively, the Energy Collector might not need to exist, a larger base energy could be provided by the command stations themselves instead of having a separate building and that makes updating old saves a lot easier.
An idea for Matter Converters:
The micro gets worse if instead of just powering on/off reactors you have to manually build Converters. What if Converters were allowed to power down, and would do so automatically if the power requirement dropped below the power provided? (maybe also a setting to control a maximum cushion and/or the minimum power provided so that a fleet wipe or loss of a Golem does not cause an unintended drop).
Here are a few ideas to make this balanced without a lot of switching on/off or required micro:
-Make Converters take some amount of time to power back on (roughly equal to the time it would take to build them, but it saves you the micro).
-Or make it so that when a planet has a Converter switch power modes, it does not allow an additional switch for some amount of time, so they could only turn on/off one at a time on a particular planet. This would also promote spreading out your power base since it could respond automatically more quickly.
-Or make the converters have a large up front construction cost so that a tough decision has to be made to add more of them, but once you have them you can take advantage the automatic switching.
