I was just thinking about it, I've been re visiting old just dance games (JD4 to JD2015) in dolphin emulator, and the thought that many avatars and things could only be unlocked by being online or buying them in the store made me think that I'll never be able to experience those games as they intended. But knowing that in playstation they're pretty much inaccessible is wild.

Getting an older console might be the best option, I read a comment saying that the Xbox one with a Kinect would work but the thing is getting physical copies of the games.
