In terms of pieces and map, it looks pretty much the same as what you get in Conquest of the Empire; I think the Eagle Games edition is still pretty widely available…
I play it like this:
Infantry attack at 2, defend at 3
Cavalry attack at 4, defend at 2 and have a 2 movement
Artillery attack at 3, defend at 5 and have a preemptive attack
Since I use CotE components, I use the income system from it, along with the cities, fortresses and roads and leaders
(and then I have 2 expansion levels beyond this by adding assorted other components)
