When I play MTW, I let the computer do everything else, except fight my battles and build units & buildings. I'm also not keen on using assassins, because they have such a low chanse of success, which is very understandable, so it seems to be just a waste of time and patience. When my empire has grown big enough (I control about 1/4th of the whole map), I even let the computer build the buildings.

I play the game in using expert difficulty level, and I'm able to win the game even from tough starting positions. Am I, however, losing some advantage when I let the computer hadle the minor tweaks, or am I losing much of the game experience?

I don't like to hassle with the minor stuff too much and I hope Rome TW will do better in this aspect.
