I have played Medieval 1&2 as well as Rome to death. I have finally upgraded my computer and should be able to run either Empire or Shogun II. I focus primarily on single player so AI is a big deal. My question is: with all the complaints i have read about Empires AI, should i bother with that game? Is the AI improved in Shogun2?

Just looking for opinions on where to go in terms of Empire, Napoleon, or Shogun2 with a focus on singleplayer experience.

Thanks!
