I'd also like to see the moon revolving around the Earth in Geoscape. Maybe make the whole background revolve slowly too as you're turning the world! That would be sweeeeet!
About the Moon base, sorry for going off topic
but one last thing. After beating it, I'd like it if you can click on the moon from the Geoscape and it'll take you to the expensive Moon base >) It'll be a little more expensive than a normal base.
Last one for sure. You won't know about the Moon base until you interrogate an Ethereal Commander. An Ethereal Base on the dark side of the Moon would be so cool
and only the high command Ethereal know about it.
