That is my ultimate fear, that the franchise goes the same direction as SimCity and tanks.
Also, I really don't like combat the way it is. I liked the idea of building armies in Civ3, I hate having to manage so many military units. I hate even more how on Emperor, the computer just has thousands of freaking rifleman and infantry by the time we get to the latter eras. In history, armies didn't last indefinitely... there either needs to be more maintainence to keep a division for centuries or just make it that much more expensive to maintain such large armies.
