Yea the NPCs in Skyrim just feel like robots.
It's not even just routines and schedules, most of them have no story, nothing to say, or the exact same things to say as other people. They don't have relationships with other people in the town etc.
I get it can be a time consuming task, but when you walk into a town of only like 50 NPCs, and they all just kind of stand around and do and say the same things, and don't react to the world around them, it is pretty boring. In a game like The Elder Scrolls, where 'role playing' is kind of the whole point, it's rather disappointing.
Take a game like Majora's Mask. It's much less an open world RPG than The Elder Scrolls, yet the world feels so much more realised, the NPCs more individualised and unique, it seems like an actual town populated by actual people. I'd rather that than scores of what looks like generic NPCs saying the same generic things.
