Just Dance series

The Just Dance series is a series of rhythm games developed by Ubisoft, heavily featuring licensed music that the player can perform dance routines to. Due to the series generally targeting an E to E10+ rating, songs in every incarnation of the series have been censored for language, sexual references, alcohol references, etc. (sometimes inconsistently) to receive the desired ESRB rating and keep things appropriate for younger players.

Censorship

Just Dance

•  Blondie - Heart of Glass: The version of the song used is a radio edit which changes "to be a pain in the ass" to "had a heart of glass".
• Katy Perry - Hot N Cold: The version of the song used changes the word "bitch" to "chick", and is even referred to as the "Chick Version" in-game.

Just Dance 2

• Avril Lavigne - Girlfriend: The words "damn", "hell", and "motherfucking" are blanked out, except for in the phrase "What the hell were you thinking?", which is changed to "What type were you thinking?".

Just Dance 2: Summer Party (Extra Songs in Europe)

• Estelle - American Boy (feat. Kanye West): This game has some additional censorship to the song from the original Just Dance 2 for unknown reasons. The verse "Don't like his baggy jeans, but imma like what's underneath them" has every word after "baggy" blanked out. The word "hell" is later additionally blanked out. These censors, however, only apply to the PAL version (Extra Songs) and not the Summer Party NTSC version, which leaves these uncensored with the ESRB's rating summary even using those as examples of "mildly suggestive" material.
