I've been a huge fan of Civ, I started playing it with Civ I, but have never liked any of the combat models. The notion of an artillery unit attacking a city all by itself makes no sense, even with the notion of withdrawing. Units need to be grouped, and combat should be executed in multiple phases ( ranged weapons, then melee ). Additionally, if a single marine attacks a tile with 20 marines on it, the 20 marines should take it out with no losses 99.9% of the time. The one on one model makes no sense.
