I made the planets take shortcuts (linear hops) by increasing the simulation speed by 10

Maybe you could speed it up by removing the massive output in the extra window and display that info in the main screen?
I heard that one of our planets doesn't patrol on the same 'disc' like all of our other planets, did you thake that into account?

Or Master of Orion?

That would be fun to make... why not?
One of my all time favorites! I played MOO1 each day the last week and plan to make my own (simplified), too.
