That may have been deliberate. DPC originally planned this game to be linked with AL so he may have thrown some easter eggs into AL with that intention. However he then changed his minds and the games are no longer linked.
There is a limited amount of assets in DAZ to use though so there will be a crossover between DPC's games and also all other games created using DAZ. The generic park, clothing shop and cafe are proof of this, whenever there's a park it's always the same asset, same with when there's a clothing shop or cafe.
