For me, i almost always lure my opponents into my base and slaughter them inside my base from cannon fire and my armies.
Then when their army is destroyed, i quickly counterattack to find that they have meager forces compared to my almost intact army.
This method has worked time and time again, playing as France on nilla.
And i advance to age 3 first though, before i do this method.
And if they don't attack i send my army to attack their base.
If they have an army, i retreat and keep raiding him until finally they get angry enough to attack. And if they don't have an army, its gg.
So how do you win games in age of empires 3 and its expansions?
