We support this with various perks in the utility tree. For example, the aptly named ‘Captain’ perk increases the bravery of nearby characters based on the captain’s own bravery. The ‘Rally the Troops’ and ‘Inspiring Presence’ perks are two more ways to build characters into leaders that improve the performance of others and make sure they don’t turn tail and run in the heat of battle. We don’t restrict you to have a captain, though – you’re free to have none, one, or several captains and lieutenants depending on your playstyle.
Basing the worldmap figurine on a character the player selects isn’t a bad idea.
