I won't write much. I have a very frustrating experience playing on basic AI settings in xcomfiles. Until I set the AI difficulty to 5, aggression to 2 and shooting to 3 by trial, error and advice, the game was strange and funny at the same time. She was no more complicated than an ordinary AI. Why not make these settings(523) the default? And I would also add a bit of chaos and randomness to the AI so that it would not be so predictable. Sometimes it seems to me that I control the actions of my units over the actions of the enemy.
