i can see.nintendo locking building behind updates. they might want to avoid people time travelling too much to unlock things. if they release a dream suite pike 2 months into the game after its release, it would encourage people to play. theyre doing it for holidays, so whosays they cant so it for upgrades? perhaps the museum can have art but they still havent implemented redd into the game (perhaps theyre waiting for post easter). one thing that discouraged people from playing NL was running out of things to eo after they TTed to complete the game. perhaps theyre trying to avoid that this time around.
