First, some villain questions:
1. a) Will the intricacies of a villain's schemes depend on their intelligence, so that there's a difference between the plots of some random street thug, an experienced court spymaster and a god of deception?
b) Speaking of schemes, I remember you talking about the investigative process in the game and piquing my interest. What kind of non-verbal clues will the player be able to encounter when investigating something? Letters, out of place items, gold coins from a specific location that were used as a bribe, etc?
c) Are there any plans to improve the observer skill in the villain update? What kind of improvements do you envision?
2. Will characters that are immortal/have extremely long lifespans(elves, magical creatures, deities, mortals augmented by life-prolonging magic) that are intelligent enough potentially have schemes that span centuries until they come to fruition? Will they be able to have numerous contingencies and back-up plans in the cards if things deviate from their predicted course? In general, how complex could plots get when dealing with creatures of vast intelligence and age?
3. How will the motivations of a sapient creature of an extremely alien mindset be simulated? Things like Lovecraftian/non-anthropomorphic deities, or forest spirits, or daemon-like entities representing some obscure sphere?
Now, some questions about magic:
4. Will there be the potential for certain magical spells/actions to become relatively common knowledge (among mages, at least) but the actual reason why they work is completely unknown/misunderstood? Say, the general consensus of why tarot cards work in the world is that Mykhanor, the God of Fate, is dispensing wisdom (and this would be the knowledge the player also has, at least initially) while in actuality Mykhanor isn't even real and the work of tarot cards is actually the product of local spirits messing around with them (but almost no one knows this).
5. How would possessions work when it comes to the player? I can imagine that completely losing control of your character wouldn't really be fun, but at the same time the entity's control of you shuold be simulated in some way.
6. Will dreams be a thing? Since dreams are an extremely common source of prophecies in fantasy, I assume that at least prophetic dreams will be a thing, but what about non-prophetic but somehow relevant dreams as well?
7. Since I assume regular, run-of-the-mill legends are also planned, will sufficiently important legends be able to 'morph' with a civ's creation myth to produce some kind of hybrid?
((Might add more questions a bit later))
