Zone of Control

[Leo Tang]

I actually liked how fort is being treated in Orbis FfH mod-mod.

They come with a fort commander, which can bombard to a maximum of two tiles away. That effectively create a zone of control. Since Civ5 will come with units that do bombard, maybe a fort can enhance their range or strength. That can enhance their ability to harass the enemy and maybe control a area of 3-4 hex

Panzer General has ZOC but it would depend on the map size and unit speed if it's really vital to ciV. PG has some really fast moving tanks and planes to deal with.
