I just had this idea.
How about having a setting where you can keep everything dark, except show all home worlds. This would keep some of the aspects of Dark Galaxies while removing the whole *‘Where the *$%£ am I’ business at the start.
A counter setting would be one where the entire star map is known, however you don’t know who owns a star until it’s within scanning range.
I would find playing either of these types of games interesting.
