Veni, Vedi, Vinci!!!
Rome take the series to a new stand point where you don't fight with just hundreds of people, but thousands. and the number of strategy involves are limitless.
Graphic are good, control are not the very responsive type you get from starcraft or C&C series, there is a "delay", but still smooth. A midrange PC should have no problem running this game at high nowadays.
However, if you play for hours, the AI sort of gets very predictable and you will easily out smart them.
If you get bored of the game, get Mod, there are plenty of choice outside.
Again, great value, great improvement from the last game.
