Too many siege battles?

I seriously doubt the AI is restricted by fow, cause that would be hard to script let alone to get the ai to recognise.

Also, if you don't spot the enemies forces marching on your cities and you don't organise enough force to combat them in time, thats hardly a game bug or the computer AI's fault.

I fight plenty of open field battles, probably just as many if not more open field battles than how many sieges I've done.

Not necessarily. The AI factions in GalCiv2 are restricted by FOW on the map, so at least one other developer has done it. I just can't tell if it works that way in M2TW, due to the erratic behavior of the AI even when they do have units or settlements where you're in clear visual range.
