Definately not true! The A.I. will attack you no matter how "nice" you are to him and in spite of your spotless reputation. In the end game,post 1800-1850 or so, the only good A.I. is a dead one. keep pumping out the panzers, howitzers, and spies and wipe him out. even if you intend to win by spaceship, you still need to hammer the A.I. into submission, or at least into a corner so he will leave you alone.
