I'm going to guess about eight turns, or cycles with one game taking about three hours, one taking two hours, and the last one clocked in at about an hour and forty five minutes. The shortest had a runaway activation card cycle for the patriots and they went to town on the Torries.
The game had five Loyalist units, four line infantry, and one cavalry. The Patriots were numbered four with two line units and two skirmisher sharpshooters. Kind of smaller games but we wanted to get a handle on the game before trying larger games.
