I can't count the number of times, in my experience with TW games, that the AI has got stuck assaulting my city/fortress and I have had to wait for the timer to run out to win the battle. I have many memories of the AI in M2TW standing just out of missile range outside of my walls shouting "charge, halt, charge, halt" (or something) ad nauseum because they were bugged and the whole enemy AI had frozen. Either that, or the whole AI army would just stand at the same spot that they deployed in and do absolutely nothing. Without the timer, I would have to replay the battle and possibly throw away a victory where (like many times) I managed to snatch victory against crazy odds against a Mongol Horde. Also, replaying the same battle until the AI isn't broken in a CA game....well, you could be replaying it a good few times.

So, I would like the option of a timer, but also the option to have no timer.
