^ I don't want the ability to romance a spirit. Their very beings are completely receptive and influenced by other people; they don't have true independent thought and desire.
Now, there are certain particular circumstances where a spirit is more independent, but that also depends on its original nature. For example, I think Justice while inhabiting Kristoff's body was his own "person," while still having those attributes that made him Justice. However, that changed when he merged with Anders, and at that point I don't think either of them were independent people.
This is the same problem that I have with the idea of having a romance with DAI Cole (in the base game). He acts and behaves out of compassion; he doesn't do things for himself. So how are we to know that he isn't with someone just because he feels that it will "help"? We can't know that. After making him more human, and after a further two years, he has that independence of self to form his own romantic feelings about someone.
The idea sort of amused me , the reflect your every wish.
Because I think it's creepy.
But I was playing Fallout 4 and there's one companion (you can't romance) who's sort of a spy , and change his face and identity, and likes to lie a lot etc...
Anyway I was musing on a romance where the LI would be like that.Someone who totally mold himself/herself on your expectations , and you're never quite sure if it's genuine or all a façade.
Now I'm picturing a desire demon doing this.And perhaps you don't know it's a desire demon , let's say he/she pulled a Cole ,and is semi humanoid.
Like I said I would find that amusing in a creepy way , because for me it would feel SO wrong.
Of course I don't think you could pull that off in a game , the character sort of molding its personality to fit the pc desires would be super hard to pull off.
