We are big fans of Piquet. I co-wrote the Anchor of Faith supplement with Mark Dudley, and I've also done some variations of Field of Battle, notably Ager Sanguinis and Ager Proelii. I also designed Jump or Burn.
We hate using rostas, especially in big games (this one involves nearly 100 units). Beads give immediate recognition to circumstances.
In this case beads usually denote unit quality.
Purple: Determined. Blue: Eager. Green: Ready. Red: Battle Weary.
It's similar for command quality (except: Superior, Skilled, Average, Poor) with the addition of yellow for Abysmal.
Black: First Fire / First Charge.
The coin counters show casualties, cessation cured disorder (house rule, where certain disorders are removed for an impetus pip on officer check), ralliable (morale chip) disorder, and out of command.
