I know is too soon but what if in a near future our beloved survivors find their way into this cheap way of keep their business running?
And with it give a little kick to the incipient economy system, bring new ways of fun and learn a bit of the most sad and dark side of humanity.
There is a lot of fun ways to apply this, one is a cheaper but not so efective or reliable kind of NPC to have, could be use in several ways as; guards, servants, vendors, gatherers, workers, sex slaves and my personal favorite GLADIATORS.
Imagine a new profesion where you are the Dominus who capture this NPCs with some type of taming ability from enemy (humanoid mobs) camp, then you give them trainning for several diferent tasks like any of the above list and after you sell them for coin or goods (whatever you like), you set the price of your slaves.
Then the friendly staff of our beloved Xsyon could add several buildings with as much as needed tiers. Buildings like the Ludus(where the slaves got trained), Massage Bathrooms (you know), Arenas(Where the Mighty Gladiators get glory or death) (and the owners get profits in several ways) (and regular players can gamble) and also cells because the slaves need a place to rest.
I know slaves is a mature themed feature and i don't have a clue which is the aimed audience for the game but i still present the idea, after all this is a friendly forum ^^
I got a very developed mechanics for this and its big, actually can affect the game in a big way so i also understand that is a BIG challenge but i want to dream.
Now i'll love to hear you guys and maybe even add more to this, if you like it enough i'll go indeep with the mechanics.
