At the very east, CA could provide the game with some kind of code that can be switched on or off via use of the 'arcade battles' button that would allow the computer to store a small database of the human player's movements in battle, and search it's own coding for a reasonable counter to that movement, so that when the computer sees it happening again in a later battle, it could provide more of a challenge by attempting to counteract a tactical movement it already recognizes as having lost to once before...lets face it, no matter what you do, the only real tactical movement the computer makes, is realigning its lines with your own to prevent you from having one flank significantly stronger than theirs.
