From memory, a lot of The Witcher 3's NPCs do the same. Many will go to bed at night, and take cover during storms.
Yeah, exactly. CDPR's attention to detail in environment topography, social strata in civilisation, and visual worldbuilding is second to none. Everything is exactly where it should be; towns and cities look like they were dug out and built to be on top of land that existed before, people live and work and speak like they would in their relative social hierarchy, foliage is distributed realistically based on soil and topographical variances. It all blends together in a remarkably believable way.
Yeah something like Skyrim has horribly inconsistent and unrealistic scale to everything in comparison. Just compare a simple forest in TW3 and then look at what one looks like in Skyrim.
