True
The sandbox elements are the very thing that makes them unique and memorable. No other game has a world that feels the same. In other RPGs, be it Dragon Age, Outer Worlds, or Witcher, The dude who sells weapons is the weapons guy and stands there till the end of time. He might have a cool story, but in the world, he's static. In BGS's jank engine, that guy has a whole daily routine, which can vary by the day, or even month. He has a place to sleep and can eat at home or go someplace to eat. If he dies, which he can unlike many other games, he will be replaced by his son, or wife. And it's not just the guy selling weapons, it's everyone in the town. Their towns may be smaller, but every NPC (barring guards) has a name, a schedule, and unique dialogue. They have personal thoughts about what's going on in the city and area at large. Add to this the persistence of the world offered by their system of having just about everything in the world being a dynamic physics object instead of static, and their last game from 2015 is still unrivaled. They could drop a trailer any time, and when they say it's from the guys who actually made Skyrim, people get excited.
