Good evening ! I'm thinking to increase the size of the galaxy and the number of empires in my next campaign. Currently, there are 8 empires counting with me but I'm thinking setting 11 including me (I don't have access to the Nakalims). I want space among the empires' systems  in such a way the colonized systems don't stay so close to each other: In my current campaign, the 8 empires are so close to each other that I can hack a home system in three turns.   Which size should I choose for 11 empires, Huge or Colossal?    

Thank you Sublustris!
