Webizen, thanks for including pics from the editor. AT has the best game editor I've encountered - not necessarily the easiest, but the more powerful the tool, the more there is to learn.
As far as the concerns about the AI, I agree with the chorus of comments about, but can also say that I've never found ANY game with AI that is truly satisfactory. In most cases, the AI plays as sort of a "hive mind" - as if you were competing against a nest of termites or colony of ants. No masterfully strategic moves or surprises, but more of an overall swarming of masses of troops. That is just the way AI is for any game. That said, if I play against multiple AI with one or two nations set at AI+, I usually have a challenge at hand. Similarly, with the game editor, you can create events or edit other factors to make the AI more competitive and give it some personality.
My opinion here is biased or course, as I am a hopeless game editor addict. I will buy the expanded game, and whittle away hundreds of hours of my life experimenting with the editor, and maybe, just maybe, even play a game or two.
