Few ideas that would be amazing for quests.
  • Would it be possible to have a setting where certain npcs would give their own unique quests? If not, even just locking quest types to specific npcs would be interesting. Aka NPC1 gives kill quest, NPC2 gives collect quests, etc. 
  • Being able to make quest chains aka a quest would need to be done before another quest is available.
I would be willing to pay as well.
