1. Factions : planned but not implemented yet ? So this plan is on a roadmap? ETA
2. How many NPCs in the world ? Will there be faction based NPCs roaming the world ?
3. Can you create your own town (faction ) and expand on NPCs supporting you or the faction you joined?
4. how many missions does the game have how long will you be busy with them ?
Hi and Sorry for the late answer!
1.Actualy there is no faction system planned in the near future
2. Actualy not
3. You can create your own Village/Town and you will be able to hire some NPC guards defending it ( usefull for pvp servers )
