Then I'll straight up say this: Assassin's Creed does cities thousands of times better, and the npcs are more believable even though they don't speak directly to you. Hell, probably because they don't speak to you.
I know it's too much to ask Beth to do a city half as good as AC's, but maybe they could shoot for eight or ten percent as good?
I think youre completely missing the point, assassins creed by design works because it is a linear game with only one role to be played, you are the assassin, who kills specific targets, and must avoid others, whilst all other characters are merely set dressing and potential obstacles to you running down a street.
These are NOT characters, they have no identity they are just puppets walking up and down the game space that disappear as soon as you get so far away from them, they are throwaways because they CAN be throwaways, notice that also there is no requirement for massive characterisation in the other notable characters in the setting because your job is to kill them, thus you get their little snippet of story and are gone, entirely throwaway.
Compare this to oblivion / morrowind / daggerfall
it is a ROLEplaying game where you decide what you want to do with the massive freedom bethesda have given you, you can be a mage, and just go about picking flowers and talking to people to find out about them for example. How do you propose that you have all the possibilities available to you in TES games when you stip out any meaningful interactions you have with anything for the sake of just displaying more crap on the screen?
EDIT: I admit im now just opposing youir argument so i will make some more statmements, I think I agree with you on one level, obviously there was a lot more effort put into the design of urban areas in assassins creed, and its obvious from that link you showed earlier this is of particular interest to you, however the sprawling urban areas are a focus of assassins creed, the original pitch that was given by whichever people formulated the idea likely included the whole parkour element from the get-go seeing as its was thoroughly fleshed out for the game, and that style of gameplay requires a vastly detailed city with interesting architecture.
What im trying to say is that AC does less than TES so it can focus more on what it does, thus magnificent cities which you can climb all over like a bloodthirsty chimp with throwing knives, however TES tries to cover a wide range of possibilities playstles and game elements, so obviously if it focuses on one more either the development costs will increase, or they will have to cut back on other areas, whilst being a consumer of games its hard for me to accept things arent good enough in certain ways, I can also appreciate the bind the developers are in. The games industry is a business after all.
