As I understand it, this is the most clearly defining feature of a fort from any other improvement. I would strongly suggest to switch this to ON. That may well clear up the capture issue. Furthermore, units with City Defense abilities would be able to make use of those abilities if the fort counts as a city.Fix the capture issue would go a long way to making this useful. For example if I changed the XML tag bActsAsCity on the new forts to true will this fix the problem of capture?
If we can find art for it surely the programming wouldn't be too tough since I can draw on the original fort programming to create an Improvement tag that makes the plot the improvement is on provide passability for ships. You'll still want to protect those ships though since they'll be vulnerable to free attack by land units. It would be more difficult to keep that from happening.Canals, canals, canals - no one has manage to get these to work. They are basically a route on land for ships. The two fort thing was probably emergent rather than programed for.
