uhm...In the current version mining tech are not revolutionary, kinda boring, but still create something interesting.
If you improve your mines, their upkeep increase, meaning you have to produce more energy. Your economy improves, but requires adjustments.
Lab techs allow you to specialize but at the expense of other domains.
None of these techs do that, though I can see why it is hard to do this kind of things with the new system.
you do know there are laready repeatables right?
