The first world have a few secrets if you join a few times. The outfit is chosed at random on instance creation (simulating it being another day). On rare occasions you can also find her outside. It's quite the nostalgic world, and means a lot to people considering some other NPC worlds (like "everything will be allright") do mention it being their inspiration. Funny enough I think I completely missed the 2nd world, I was too used to go to Sector45 instead. (that's especially weird since I know the "Lua in wonderland" worlds...Dunno if it counts as NPC world per say but it's an interesting take on storytelling) 3rd world is fun, that's it, would recommand as an introduction to VRc NPCs because it's just silly! xD I don't remember 4rt world... 5ft have a whole series now, "situation voice" are good ASMR experiments. Just don't go to the cooking one if you easely get hungry... ^^" Ah yes, paying to unlock more poses around the map, that and posable dolls are so common it's a bit...weird Kinda surprised garage house/club were not included, they're super nice maps to hang out there. SRS cafe also feature some little NPC-related things I will not spoil, don't forget to look around for secrets. I don't know if that count, but as "weird NPC worlds" goes there's a whole "ready grow" series of game maps where a NPC grows to get in comically large situations as you progress. Another, more controversial NPC world back then was the Pokky-game. It's author is trying to make a new world with even more interactions, for better or worse, and a large choice of NPC.
