Although it's a secret that's been hiding in plain sight in many ways... here's a thread on BGForums from 2002

viewtopic.php?t=218
A quote from past-me: "Hey, I started planning Galactic Ruler in 1985, I'm sure another decade or so won't hurt"
It was also mentioned in 2005, "Yes, way back, in the mists of history, SR2010 was to be released in late 2002, and Galatic Ruler in 2004"

Or in another thread after SR2010 was freshly released, where I said: "Somehow I have the feeling that humans will be walking on Mars before we end up getting 'Galactic Ruler' finished"
We'll be talking a lot more about Galactic Ruler in the coming weeks. We are looking forward to getting the feedback and input of our player community into the concepts, ideas, and features we're planning. So stay tuned, and join the discussion here on bgforums, or on the Steam discussion forums, or on Discord. If we stay on target we'll get GR out before Elon Musk walks on Mars.
Thanks everybody for your continued support, the ride continues.
