Not to mention phantoms, where you can see other players's ghostly images occasionally moving around the world. Other subtle cross-over features exist too. In Dark Souls 1 you are able to hear other players ring a bell after defeating an early boss. A rare mob can also spawn in your world when a player dies with many souls (currency), or loses a powerful item. It definitely does much to make the world feel less lonely.
