That's the Vanguard way as well plus they are in the open world.
They can go this way http://www.youtube.com/watch?v=p5lXH4PIxww where everything you see in this vid is player made,wallpaper,bricks,paint,mortar every single thing is player made.
Or they can go this way http://www.youtube.com/watch?v=MiBUbMIk5uM if they do have housing this is the way they will go IMO.
Yeah Mortal's houses are in the open world too. They also have cities too with walls and major buildings.
Here is my ideal system (based on SWG and Mortal Online):
- "Settlements" can be created in most flat, open areas in the world that aren't in proximity to major landmarks. There will be protected areas of course where settlements cannot be built. This will require a MASSIVE world with a lot of open area.
- Hostile mobs will still spawn inside settlement areas (not houses) unless the settlement's leader employs NPC guards, which will attack and kill hostile mobs when spotted on their patrols.
- In order to create a "settlement" you must be a guild-leader. This will be your guild's settlement. Depending on the size and influence of the guild limits the size of the settlement.
- If a non-guilded group or individual want a house they will buy a land deed from their nation's magistrate for a LARGE amount of money which will allow them a very small area for a single building as long as it is not in proximity to other guild settlements. Guild settlements however WILL be able to encroach on individual homesteads.
- In turn, guilds are not easy to create, they require a minimum player count and a large amount of gold to be paid to your nation's magistrate.
- Guilds can allow non-guild members to settle in their territory, and can impose taxes.
- Houses/buildings take a LOT of resources to create and a LONG time to build.
- There are different types, styles and sizes of houses that anyone can build if they have the blueprints for them.
- Houses each have an owner, co-owners, tenants and guests lists (with limits on number of each depending on size)
- In order to level up your settlement you need to build certain buildings (as well as meet guild population and influence requirements) like Tavern/Inn, Blacksmith, Lumber Mill, Town Hall, Walls, Keep, Castle, Farm, Windmill, etc.
- Settlement levels are (from lowest to highest): Homestead, Hamlet, Village, Town, City, Capitol (special circumstances must be met).
- Settlements can be populated with NPCs that do certain things (town crier, barmen/maids, bards, vendors, miners, workers, guards, etc.) all costing money over time and limited by the level of the settlement.
- Houses require a lot of upkeep and if they are not met they will fall into ruin. Any member of the town can build on top of a ruined house, using it to mitigate the resource requirements for the new house (using the older lumber and nails etc) and claiming it as their own. House owners can repair ruined houses for the same amount of mitigated resources. it all depends on who gets to it first. A ruined house will stay on the server for 7 real-life days before disappearing completely.
