I'd love to see some life in my house other than my dog standing in one spot as if it's stuffed. How about selling a pack of NPCs of particular faction. For example, for 5k Crowns, you could sell 10 NPCs with varying personalities and pathing options. It could include five guards, two servants, one stable master, one commander-like person and one cook. Or you could sell them per NPC. It'd be amazing to see some NPC guards up on towers or guarding walls or something.
