I used to play ddr when I was younger. Now I play MoonRider in VR(you may have heard of beat saber). I think it’s even more fun and harder exercise if that’s what you want. It’s also cheaper, you can get a quest 2 for $150 which can also do everything a stand-alone VR headset can do. There are actually a ton of exercise apps/games, though I’ve never tried any.
