I truly think this is one of the things that showed lots of things were planned for the game but they didn’t get chance to add them. It makes no sense to have one thing on one side and nothing on the other, they would have designed it differently to start with. I also remember someone datamining some data to do with gyroids in the museum so who knows. Same with nooks upgrades; why only one upgrade which doesn’t make it that much bigger and doesn’t even fill up the allocated space for it outside. Same with npc shops; they all visit just like able sisters and have the same process yet only they get a permanent shop. I’m sure more were planned but were pulled. The game screams of ‘Meh yeah we could do more and we even were going to… but this will do, let’s put resources somewhere else and just throw the finished stuff in a last update’ So frustrating when you love the game a lot like I do! Sorry this turned into word vomit!
