Welcome to the forums Ashbery76, it's good to see you here. Since you mention the AI, try a game on Hard and let us know what you think. While not being very good at defending yet, I think the AI is already pretty decent in attacking/raiding. In general, we estimate the AI to be operating at around "one-third" of its maximum potential when we reach the final release. Also, the AI plays by the same rules as the Human player (i.e. they don't cheat), by the way. Ground combat is not in yet.
