I'm actually a fan of the addons..... playing vanilla all the time would e like being stuck in groundhog day
Different addons each game make you tjink differently, even with the same races....... anyway i digress.
I liike the concept, ............what about using the addon that gives ships experience points, and when you have killed you neighbour, a wormhole opens to a random cluster.... you go in and join their battle.
this would give a 3 way battle but chances are by the time you get there, one would be supperior to the other.
Just a thought
