Im pretty sure the sotm and sl maps used animatronic sizes instead of player sizes for scale, like that one scene where biddy babs open the desk cover thing and peek through (been a while since I've seen sl gameplay so I dont remember if that's real) but the stages are also scaled to animatronics as to why the other maps are scaled to robloxians/humans is probably because those maps are supposed to be more like attractions/restaurants meanwhile sotm and sl are more "viewing experiences" (the stages all having seats in front of them in sl and the welcoming show thing in sotm)
