I trawled through the achievements and discovered an easy one. Make and preview a galaxy map. So i popped over into the map maker and played around with the sliders and made an absolutely ENORMUS Galaxy. It had over 250 Planets, too many stars to count (because planets are quickly estimated while stars are not) I can only imagine the Months it would take to actualy Play this map. The game created and loaded this monster in the same amount of time it takes to make and load a normal map.
