Well, I liked the Great Wall in Civ 3, and I thought the perimeter Def would be more useful and realistic this game...but...gosh..it's near useless! I suppose the Great General pct% upgrade is nice...but a wall is hardly a candidate for upgrading tactics.
Barbs are generally never a problem for me, and if they reach your core, you need to send more defensive scouts out.
Here's how I think the Wall needs to be upgraded to become more realistic and useful. (So if someone could pass this along to Fixaris for consideration..)
Downgrade the GG Pct. 50% mabye.
Make it take three turns for barbs to pass through the wall.
Make anyone (friend OR foe) on the INSIDE of the Wall have both a road bonus AND a Defensive bonus. Then, the wall would become of tactical use.
