Get a wii. They are really cheap and support all just dance games up to 2020. The wii also has so many other great games and can play all GameCube games. You can also easily mod the wii and add back all online functionality. Also make sure to set the censor bar position and widescreen settings to the right ones, I’ve seen so many people with the wrong ones and it only takes a couple of minutes and makes everything more enjoyable. I would also suggest for you to buy a wii to hdmi so you can connect to a modern tv.
