I started playing cIV yesterday after playing ciV for about a week and deciding cIV was probably better. Gunpowder units bypass a cities' defenses, so I decided to wait until I discovered gunpowder and upgraded all of my soldiers (besides a few units of pikemen to stop Persia's mounted riflemen or whatever) to grenadiers and made an army of riflemen, grenadiers, and the occasional French Musketeer. Persia had a lot of Longbowmen defending a city, nothing else. I don't know if I was attacking wrong or not, but apparently you can only send one unit at a time to attack a city, so I lost around five units of grenadiers trying to attack two units of Longbowmen. Anyone have tips on attacking cities? I know everyone has a different attacking style so I'd like to hear from as many people as possible.
