A suggestion/feedback.
More options for slower computers.
I have exactly 4GB of ram and the game runs slow for me. I can run it, but it it slow. One of the first things I did was go in to the options to try and reduce things as much as possible; but there are not many options to reduce.
Thus my suggestion is to add options that will have the game run better on slower computers
Examples:
always show planets as icons
never show background planets
turn off videos
etc
