About the campaign phase.. Just as I promised..

Factions

As I said before there are 2 types of factions: major and minor factions. During each turn, players of the major factions, must elect a leader for that turn. The leader then can determine how the money will be spent. There are also bonuses if he wins a battle during his term. Though, if he loses then there will be severe penalties as well. All players who picked minor factions will become leaders automatically(because there can only be one player for each minor faction).

Although minor factions may look weak there are ways how to protect yourselves. As long as minor faction is neutral it can not be attacked by anyone. This means however, that they can't attack other players as well. Once they pick a side(whether it's Roman or Carthaginian) they can attack and they can be attacked. Minor factions can declare themselves neutral again when ever they want. They can also switch side when ever they want. Switching a side or declaring yourself neutral come in effect next turn though.

So, there are several ways to play the game. If you want a co-op between other players from the start then pick one of the major factions. If you like to hold back and prefer diplomatic manouvering then pick a minor faction.

Buildings

Since I want to keep the game focused on battles then there are just few buildings that the leader can build in order to improve the faction.
Infrastructure - This means roads, markets etc. Ifrastructure determines how much gold each province produces. There are 10 levels.
Barracks - They can only be built in the capital. Barracks give free units for the defence of the capital. Each level give 2 random units to represent volunteers who have joined the army. Those units are generated only when the capital is under attack. There are 5 levels.
Ports - They can be build in every coastal province. They generate money abd allow the construction of warships. There are 5 levels.

I'll post more when I have the chance but now I have to go..
