Based on the Open Beta Point System, playing the whole box is around 460 to 470 points. But since the cheapest ship is 80 pts, you can claim that it's a 500 point engagement.
What has everyone else been playing at, point wise? How have 1,000 point games gone over?
I am planning on playing a 600 or 700 point game tomorrow night. With the squadrons that I have put together that gives each side about 5 or 6 ships which is plenty for an evenings battle.
