I agree that we should have had more buildings from the get go. As the game is, I don’t get quite the feel of a “village,” like in previous installments. Even with all the work to make my island feel warm and welcoming, the lack of real buildings makes ACNH really feel like a deserted island, and not in a good, relaxing “vacay” way. While I designed my island with plenty of room to redesign in case new buildings were ever introduced, I understand why many players would be cross if they had to redo their island 1 1/2 yrs later.
While I am in the standalone Roost camp, I would not mind it in the museum, so long as it is not stuck in a windowless basement in the far corner of the fossil exhibit— that’s horribly wrong on so many levels. It would be great if there was a cafe entrance on the mezzanine landind between Blathers and the Art Gallery (with another entrance to Celeste maybe?), or a front staircase a la our house.
