When at a game store, we stick to 1000 to 1500 points, as this can easily be fielded withthe typical fleet box.
At home, when playing just to play, it's usually 2,000 poits. this lets us throw in a dreadnought and a buncha little ships.
If we're at home and play-testing, then we do a battle at 750 points, one at 1,000 points, one at 1500 points, and one at 2000 points. Since we have a huge table (12x4) and an abnormally large play test group (8 to 12 of us), and a decent sized minatures fleet :roll: ; we can squeeze in 3 battles at a time.
Although, I'm thinking NashCon / Origins may be a bit different:
750 for round one, 1,000 for round two, 1750 for round three.
