Sadly, I just can't get all that worked up about Kingdoms. I haven't even played through all the vanilla campaigns yet, so the last thing I really want or need is a whole lot more to plough through, then mod to make more difficult, remove the bugs, balance the units, etc, etc...

What I'd like more than anything else is a really challenging AI; one that I don't have to artificially enhance with money scripts and spawned garrisons. These can only do so much anyway, since no matter how many stacks the campaign AI throws at you there's a tried and tested method to smash them to smithereens on the battlefield....

Maybe Civ IV Beyond the Sword is a better option.
