What part of “it’s an online game“ did you miss? The “online” part? It’s not just a game for you. It’s multiplayer. In the off chance someone actually wants to use a vendor, learn something, or follow plot NPC stories, the NPC needs to stay there. But you know, feel free to glaze over those details. I didn’t call it “just a game.” Fallout is single player. You don’t need to consider others in that. Same with Dragon’s Dogma.
