QB AI is far better than in CM1; i mean yes the AI is scripted but to script it is really easy and you can make up to 5 different plans. When the game starts the AI will choose one of those 5 plans so one battle can result in 5 different battle approaches.
Usually, i am talking about CMSF here, QB have 3 plans for the AI but you might make some other AI plan in the editor to sum them up to 5 as i said above.
By the AI plan now the AI is really interesting even on the offense
