I've started with the dwarves. I wanted an original idea for them, in fact, I want different ways to play for all factions in the mod, so I made a new system for the dwarves.
My idea is: They won't have buildings, you'll start with a "mountain" as fortress that you'll improve, building upgrades that will improve the fortress such walls, towers, rooms etc.
Of course, the towers will shoot to the enemies, the walls will make you able to put units on them, and the rooms will make you able to build new units.
I made that because I think that the dwarves should be a faction centred on attacking and not on defending or resources (I'm still thinking how will they get them, perhaps the fortress will be able to be upgraded to make more resources... I don't know yet.)
Also, I the minifactions will be a separate building from the citadel. Anyway, those will be connected as tunnels, so your units will be able to go through it.
Well, that's all. Let me show you ONE screen, only one yet. I'll show you more.
In this picture, the mountain fortress is upgraded with the walls (that's everything I made so far)
Also, there are some belegost soldiers there. They can be upgraded with a lot of things.
Its fun, if you reach population of 250, you will get a prize
