Social interactions, and that includes romantic ones, are such an integral part of human life, and, an open-world epic RPG seems a lot less real, at least to me, when there's a complete lack of NPC relationships and interactions (whether they be friendly or romantic.)
This is sort of verging on something that could evolve into off-topic and real-world discussion.
You can't have it both ways... either you want to "make it real" or not. Having a medieval setting in TES doesn't really help your cause. Think for example, the Holy Inquisition and the burning to death of homosixuals. Imagine the reaction to implementing that well-known historic fact into a TES game (which would probably cause much more of an uproar vis-a-vis the depiction of a woman being burnt because she's a witch, but I digress...)
Funny thing is, the Argonian Maid book in TES depicts inter-racial relationships somewhat accurately, in that the lords would incur into sixual relations with maids/slaves, but not marry them. Even among the same race, some unions were seen as no-no's (English-Irish-Scottish, Catholic-Protestant, etc...)
I want to play games like TES to fight ogres, dragons; loot the dead bodies of the enemies I killed, save the known world from evil daemons, shoot fireballs from my hands, etc.. not to delve in real life.
