If you understand German, there is a Thread about this.
http://forum.modding-union.com/index.php/topic,30507.0.htmlThat´s the Link.
On page 4 is the last real Concept and yes, it´s mine
In short I want to build a Village like Edoras, costs are 800.
At first it only give 30 ressources like a farm, but you can build little Towers for 100 ressources per Tower. They can´t attack themself, but with troops in it.
With the first Upgrade they get a very little own attack.
The second reduces the costs of troop Upgrades for 5% (10% and 20% with two or three villages)
Third upgrade give you riders level 2 a new banner and give them +10% Speed and can ride over more troops by the enemy, but not them with the Bows, they make more damage.
Fourth upgrade give more strength to the village.
They cost all 500.
Last upgrade, you can get only with Theoden without his bane and cost 750.
It makes the four Upgrades before even stronger.
I hope you can understand it.
