As a major long time fan of the game Risk, I think they have done a great job with this game. After playing in the beta for the last week, I have found that the AI is pretty comparable to what you would expect from an average human player. The AI seems to "understand" the basics for good placement and strategy, yet is not overwhelmingly strong to the point of being unbeatable. I have only lost once so far, but I am a very experienced player. I'd have to say that I am enjoying the game and can't wait for it's release.
