barricade

[jacomanring]

In civ 3 (or in one of its exp) there was the Barricade improvement, which was to build over an existing fort...it acted like a fort (def bonus) but has another cool feat: it caused enemy units within a one plot radius around it to attack barricade (if there was any unit in it)...in short, if you wanted to pass throgh a barricade and there were not enough space to round on it, you had to attack that heavily defended tile (which is the actual fortress purpose...).

I think it would be great to have this feature back (since it seems it only existed for a shoooort period in civs )!

area of control would indeed be nice. create your own chokepoints!

I find fortresses to be utterly worthless without the zone of control rule.

Except in the erebus map type, where the excessive mountains often create chokepoints.

Yeah but that would further nerf the AI, IMO.
