RTS for New Vegas

You can dynamically place houses, stores and objects, recruit villagers and merchants.
Random bandit raids or animal attacks.
Everything you place is paid for with gold or firewood.
The default is to pay with firewood and if you don't have enough to pay with gold.

When the mod starts, you will be given 3 food objects.
A RTS Controller and two RTS Scroll objects.

For your convenience, you should favorite and hotkey these items.

To access the settings and tutorial, press either RTS Scroll objects four times.
There is a TUTORIAL for placing objects and another for a House.

There are three classes of Merchant; blacksmith, General store and Apothecary.
Villagers who live in a store will automatically work as that class.
There are five merchant inventories for each class.
The merchant will randomly be assigned one of those inventories.
Merchant inventories reset every day.

So you could have 5 merchants with different inventories, or 10 merchants assigned to the same inventory.

You can recruit upto 200 individually named NPCs.
Villagers pay taxes of 10gp per day.
Villagers can become followers. (They are leveled NPC's, min 10, max 60)
Villagers will forage and harvest plants in the area.
Villagers not in combat will now heal 5pts per second. During combat they heal 2pts per second.

Four Militia Squads. You can have all your villagers following you at the same time.
You can tell your squad members to be essential or killable.
You can tell them to move out of your way.
You can tell them to harvest plants while following you. Butterflies and fish collection can be toggled.

New Orders> Assign uniform ------ New Orders> Done assigning uniform.
To assign a uniform, tell them you have a new uniform, it automatically forgets the old uniform.
Then give them the new armor, then tell them you are done.
A uniform can have upto one bow, one shield and one melee weapon plus other armor and jewelry.

If they already have the item, you need to take it and give it back to them.
If you don't assign a uniform, they will wear the item(s) you give them.
If you assign a uniform without a helmet and then later give them a
helmet, they will wear the helmet till the next time you change cells.
If they have a shield assigned as part of their uniform and they equip a
different shield, the script will make them switch to the assigned
shield. Same for bows and melee weapon.
If they equip a spell, staff or torch, the script will not force them to change items.
