doesn't this actually improve immersion
Bar the final dialogue part thingy but that's nto such a big deal
I would be rather upset if vampires were meant to be slaughtering whole towns and I'd find the townfolk merily walking around again every time I left town
Except that's exactly the problem.
Once the combat is over and the vampires are dead all the townsfolk are merrily walking around even though half the village is dead, including the farmers and hunters that put food on the table as well as the blacksmith and general merchant.
You've got a town that should logically be in extreme disarray as all major services required for survival are no longer available yet townsfolk are merrily walking around.
If, after some time has passed, those vital townsfolk were replaced by generic replacements then it'd make sense again. The town has suffered a major tragedy but it has recovered and life goes on, Skyrim is a harsh land after all.
But that doesn't happen. The towns never recover but they never die out either. Nothing happens. The entire town goes on as if they still had farmers and hunters to put food on their tables. As if they still had a general merchant to buy their daily goods. As if they still had a blacksmith to repair their tools and forge new ones.
