We are trying to approach NPCs realistically.
Yes, they are populating towns, however via code we will be creating simple artificial intelligence for them to make it seem as if they are actually living out their lives. Waking up at dawn, opening shops, shopping, guards training and/or going to their posts, then going home at night, etc. It is a long process, however.
In terms of dialogue, we may give players the ability to interact with random NPCs and giving NPCs a database of random tips and quotes to help the player. Things like:
- "I suggest you go see <insert name here>."
- "Hail, friend! Have you seen the exotic goods here? They've cut the prices by over a half!"
- "I hear that a witch resides in the east."
- "Try NOT to die."
Quotes like that. They're not in the game. They're just examples. Guards are present in the game, and thus far (in the Prelude), you do involve yourself with guards both with them being hostile and you aiding them. As for the long-term, it is something to consider, but also something I cannot guarantee.
For your last point - it is unlikely this will be implemented. However, in single-player (a mode we intend to implement in later versions, my apologies to those who hate multiplayer, you'll just have to wait), I plan on designing a mercenary system in which you can buy out foreign slaves (amazons, barbarians, beasts) or have timed mercenaries that represent the other classes.
