In my first game with G&K, the AI took another AI city with naval units. In general, the AI plays aggressive defense with its naval units, especially via the use of wolfpacks. But in games on Continents Plus, I've noticed very little of the expected attacks on cities. Does the AI need some tuning in this area, or have I just had an oddly defensive run?
Txurce I know what you mean it's an issue that is actually intensified for Continents+ mapscripts
and why I have switched to Continents.
The problem I have noticed and I wish I would have taken a screen shot now, is that the AI generally has problems on complex coastline shapes which are more predominant on Continents+. Shapes like Peninsula's combined with a city on a hill and a bay, things like that.
In my last game, literally three different AI's tried the whole game to capture an Incan city via naval assault because the Incan's were weak and exposed. However they could not organise themselves properly to take it. Three different AI's tried it in three different eras. They just couldn't do it and the attacks stalled and they gave up.
This is why I have moved back to straight Continents map where the coastline shapes are a lot simpler. It's not so bad, Continents maps are still interesting enough. Totally forget mapscripts like Perfect World that the AI just cannot begin to fathom the complexities of that map. These are great maps but if the AI can't play them there isn't much point.
EDIT: I also think there may be a bug with Continents+ and setting the world age. What I do is to set the world age to 5000BC to create less complex mountains and hills for the sake of a better AI, but I think I only notice it working on Continents, not Continents+.
