I just want to add, it is a fun way to play the game. It gives you a sense of wonder as the map is revealed to you.

Basically for those who want to know, this is a fog of war mod. The galaxy is dark/blank until you explore and reveal it, or make contact with other empires and gain more intel on them, revealing what they know. Other than what you can see around you the only other thing you can see is the nebula names, so you can sort of make out where you are in the galaxy but seeing the name layouts.

Its completely dark, You only see what you discover.

This sounds interesting, could we get a picture of how it looks?
