I was just being a vegetable here for a while, and then...
An idea came up:
A city war mod
What if the map of the game was not a full land, but a city? A huge ancient city, that would be in a gang war, and the player would be a part of one of those gangs, looking to have full control over the city.
The map work the same way as native map, but inside a great city, and forests, hills, mountains would be replaced by buildings, streets, ruins. And castles/towns/villages by other important structures like gang hideouts, the government headquarters, prisons, et cetera. The city would be showed in a smaller scale on the map, and when joining a battle, the scale would go to natural, so if you, for example, start a fight close to the mayor's palace, the battle map would be near it, but with the building on full scale.
The factions would be:
1 - The City's government
2 - Gangs
3 - Some revolutionaries looking for civil war
4 - Covert forces from another city, looking to conquer this one, something like spies recruiting the populace
And then the player would join one of those factions, to struggle for the power of the city. And, eventually, when he made it, there could be a second phase, one of world domination, when the map would expand, and the player would be able to start conquering other kingdoms in the more vanilla style.
The concept is to start lowly, inside a chaotic city, and reach the power inside the same city. The second phase is not that important.
Recruitment would be in places like central plaza, tenants, hideouts. Weapons and items would be bought in several places in the city, like weapon shops, markets, illegal shops for the more hardcore weapons (because it's more of a hooligan war than guns/swords etc).
Battle would mainly consist in fighting with homemade weapons, in certain degrees, because the government, for example, has more things like police batons, or some other variant (it depends if it will be set in a modern or medieval, ancient world).
And there could be also an army invasion, that is out on campaign (the city is at war), and comes back when the city itself falls in complete anarchy [that would happen when one of the gangs reaches power, or the government is beaten].
Campaigns would be when the main leaders of the gangs would join they small groups of soldiers (the concept is not to surpass more than 100 men in a party)
That is the idea I had. The main points, again:
1 -
The map would be a city in a bigger scale, but yet not the natural size
2 -
The war would be between several factions inside the city, looking for complete control of it.
3 -
Recruitment and trading would be set in places inside this same city.
4 -
The map would have great buildings of the town, like icons, that can be accessed and seen on natural size on battle map
5 -
War is fought with homemade weapons and not too great armies (yeah, no four thousand soldiers on a campaign)
6 -
Campaign with leaders of gangs/officers of the army/police
7 -
When full anarchy came to the city, it's army would come back to seize control from the gangs (boss-like in this stage of the game)
8 -
Finally the city is conquered, but then, the conflict gets larger, as you discover that the world is big, and that there are other cities and nations to conquer, taking the mod to a second level of gameplay, closer to the vanilla concept, leaving city seizing back. Or maybe even taking the fight to other cities in the same country...
That's pretty much it! Is it doable? I find this idea most fun, and would like to play something like this, but I don't have great modding skills (only a moddeler), and would need someone who is interest in doing something like this.
