If you're a Britney Spears fan, you'll love this dance-video–like game. You are auditioning to be a backup dancer on Britney's virtual tour. To play, you can use either a dance pad or hand controls, but it's much more fun with the dance pad. Step on the pad's symbols and your on-screen dancer moves in time with the music; Britney herself coaches you through the routines. Points you acquire can unlock behind-the-scenes footage. The game also has a fun immersive video that lets you control different camera angles. Only six songs are included, though, and dancers would benefit from a tutorial mode.
