Playing civ by multiplayer seems fun.
I started playing Rome total war: barbarian invasion (it's about the late empire). The roman empire is split between west and east; I have choose the west roman empire. There are several minor barbarian kingdoms in my border ((alamani, franks), the celts in Britain (I'm in war), the berbers (in north africa and we are in war), and east roman empire (my ally)
So, I start with a huge army with good units inside cities and just one field army; I don't have money and by looking at the budget page, I see I will be in debt in the next turn. So, I decide to sell several buildings: in the smaller cities, I keep only the traders (that increase the revenues). I decide to also keep 6 cities (each in a different area of the empire) with the ability of building good troops, just in case. And in each city I will build units of peasants to freed the good units and still keep units in the cities. This way, I passed from 1000 denari to 23.000. I don't make any religious change: everyone will follow his own religion (I have already problems enough).
First turn: I have 19.000. Not bad : half the money was spent with the new units. I continue like this for another turn, and 3 cities revolt (1 in Gaul, another in Germania and another in the danube). I use my small field army who join the units that we expelled from the city from Gaul and I make a siege: next turn I attack the city and my comitatensis (good foot units) win easily the peasants (since I had sold the buildings, they can only recruit peasants, beside the chief who have an elite unit). I have 3 choice: forgive the population (I earn very few money), sell half of them as slaves ((half the population is divided in my other cities and I earn more money) and exterminate (kill 90% of the population and earn a lot of money). They are traitors, so they will pay: exterminate.
By now, all my cities have a huge number of peasants inside, so all the good units they had form 3 big field armies. Two go to Germania, and conquer the rebel city easily; the third army go to Britain to take care of the celts. My financial problems are finished: I don't earn money, but I don't loose any too.
My campaign in Britain seems easy: my field army receives reinforcements fro the local cities. I meet a small celtic army, and I find a nasty surprise: they have chariots, and have good moral. They send their peasants in the front line so, my archers won't hit their best troops. My comitatensis smash their infantry, and my 6 units of light cavalry isolate the chariots. I win, but this won't be easy. In the next turn I find their great army: I have receive reinforcements (some more cavalry and archers). This battle is actually easier: they simply charge without much tactics. They nearly destroy my archers who were in the front line, but there already disorganized and my army surrounded them. After that, in the next turn I conquered their city. I'm feeling magnanimous (they aren't traitors, they are an enemy), so I decide to sell them as slaves. And then my army goes to Ireland.
My armies in the continent were lucky too: they conquered the alamani (I was in war with them and I only sold them as slaves- they are a fair enemy). I conquer the last rebel city (and I exterminate them). I'm now in peace in most of the empire. I will not attack the barbarians in the border: they could have attack me when I was in trouble but they respected peace and made actually some trade agreements: I couldn't ask for better neighbors. So now, I build markets in all my cities (or forums or some other building that earns money), and earn 5000 denari by turn (an elite unit cost 500), so my financial problems seem solved for now.
So, what will I do next? Wait for the next chapter.
