How about this..
Recruiting for the Dyna takes place in the forum in 2 story based threads - 1: Forces of light -2: Forces of darkness. Develope the personalities and hierarchy on the threads.
A fast moving, hex grabbing set up with 2 home planets and a five stage base defense for each side, that increases in DV value as u get closer to the opponents home world, which will have the highest DV.. the idea will be to take the bases in assending order and then the home world and maintain a supply line that runs from all the bases to the homeworld..when the supply line is cut , it will need to be reestablished before any attacks elswhere on it, can proceed.
Just an idea
