Controlling the map and maintaining vision is crucial for strategic advantage. Use your Explorer and early military units to scout the map, locate enemy bases, treasures, and Native American settlements. Build Outposts or Trading Posts on trade routes to gain vision and income. Controlling key chokepoints or resource-rich areas denies them to your opponent. Knowing where your enemy is and what they are doing allows you to react effectively and plan your attacks or defenses. Don't let your Explorer sit idle; keep them scouting throughout the game. Vision provides information, and information is power in Age of Empires III.
