Master of Command covers The Seven Years' War, which was one of the first more global wars, and resulted in the rise of Prussia to a great power. In the game, you can choose between 5 nations, each of which have 3 campaigns (you need to finish the first one to unlock them all), and each campaign has 3 acts. In each act you are moving a single army around a procedurally created map, and interact with map points like settlements or forts. You have only a limited time until you need to face the main enemy on that map, so you need to gain strength by fighting, looting, and various map events. Every battle involves a Total War like real-time fight, which you mostly win by breaking enemy morale. You have usually a lot of infantry, some cavalry, and some artillery. Some fighting is done by lines of infantry firing muskets at each other, but there is also melee combat.

In each act you both grow your current army in quantity, but also in quality. Battles give experience, which allows upgrading of units. You can gain items as loot in battles, from map events, or buy them in cities, and those items give bonuses to your regiments. The scale remains reasonable, with a brigade having up to 4 regiments, and you typically growing from one to three brigades in act I. Learning how to play is easy enough, learning how to play well isn't, and you might actually want to start this one on easy (Lieutenant), or with at least the "Early Campaign Season" bonus modifier active.

Different nations focus on different things in their armies, quality or quantity, infantry or artillery, and so there is some replayability. But this game is also fine to just play one or two campaigns and be done with it, if you don't want to go deeper.
