Guild exclusivity is actually what I had in mind. Sure, there’s nothing that significantly changes the main quest in TES games (and I think I misremembered how much blocking is there in previous titles) but that still counts for me personally. Self-imposed role play is fine in general (I do it all the time in games in fact) but I still think that lack of reasonable requirements for some (optional?) content makes the world feel more generic and player-focused than I’d like.

Thanks for the reminder though.
