What do the difficulty settings change?
Difficulty influences the size and makeup of your initial forces. For example, the first non-tutorial mission, Crossing the River Arar (see below), includes two units of Auxiliary Infantry and three Legionaries on “easy”, one less Auxiliary Infantry on “Normal”, and one less unit of Legionaries on “Hard”. The enemy generally has additional units on harder settings. RogueImpaler notes: “Enemy villages will produce lots more troops on hard also.” Less obviously, on harder settings the enemy’s AI (Artificial Intelligence) is better. Centurion, on harder difficulties: “The AI was employing better tactics such as flanking my archers by moving through woods, but the blatant change was that I had less troops starting and there seemed to be more enemy troops. I thought arrows from enemy archers/mounted archers inflicted a little more damage.
