The kids and I can't figure out why we "upgraded" from 2019 to 2020. It's the same game, with only minor differences. Just Dance is in dire need of an innovative change because in its current form it's stagnant and boring. Buy this on sale, or just stick to 2019 until we find out if 2021 will change the formula. It's definitely not worth upgrading from a previous version.
I didn't give it one star because Ubisoft is still releasing this game on the Wii, and you have to give props for that.
