But I'm not sure about what is the most immersive way to do it.
Currently I'm thinking of having a plaque/sign/object outside the player owned house that the player can "activate" to start the renting mod off and click it again to stop the mod.
But when the player gets paid I've currently got the gold going straight into the players inventory each day. Other ideas I've had are to have a sack or chest outside the house that the player can access as the rent accumulates like in Fable, or the gold could be sent to the Imperial Office of Commerce where you get the first IC Shack from.
What would be the most immersive way to start the mod and then receive the gold each day or week or whenever?
