In Pirates of the Spanish Main, players make fleets of ships to sail to different islands looking for treasure. The goal is to use your ships and crews to collect more treasure than your opponent through exploration and battle.
In Crimson: Steam Pirates, things seem a little more oriented toward battle, as campaign and multiplayer scenarios appear to change up the objectives. The mechanics of ship battle work so that each player takes turns deciding actions and then all actions are resolved and animated.
