Probably a better idea to have it place a satellite at an ASTEROID field, rather than a MINE field, but anyway...
I'm at the end of a 100+ turn (devnull mod) game, and as I'm going around conquering the galaxy

, I've discovered that nearly every other empire made pretty liberal use of mining ships for asteroid fields. I never did it for mine because I was under the impression that it was pretty much a waste of time and energy.
My question is: is remote mining really worth it?
The answer may vary stock game vs mod. I know that DevNull mod has specially-designed ships with a 80% penalty to combat, max 2 or 3 engines, but also a 90% reduction in maintenance that may make the whole mining thing worthwhile.
