One major difference was the locations. Meroe was built on the bottom of mountains and thus had a steady amount of rainfall, due to which the soil was fertile. Other cities in Egypt depended on the annual flooding of the Nile River in order to have good soil to plant and grow food needed for survival. This kind of flooding was really important and hence Meroe was important.
