We played a four player fleet action a couple of weeks ago. It was FSA vs Empire of the Blazing Sun and Brittania.
Since JM wanted to go full fleet sets, we were stuck with making up a fleet from my Predreadnoughts. I have 3 BB's and two Cruisers that matched point wise, but is off balance for normal fleet requirements.
My Cruisers sunk so fast I didn't even get pictures of them in action. Meanwhile the BS frigates had obliterated a squadron of FSA Frigates, leaving only some sad bubbles.
On my side, the Brits, closed in trying to overwhelm my three BB's with too many targets and reduce my long range gunnery advantage.
On the other flank, the basic BS and FSA fleets had fought pretty much to a standstill.
We met yesterday to finalize plans for a 6 player economic/political campaign based on the Dystopian rules. More to follow in the future on that score.
