Bad Export for You: The first two games are this, depending on who you ask. Removing Hiro's cigarette, censoring certain lyrics, cutting out endings, etc.
No Export for You: The aforementioned Bust a Move: Dance Summit 2001. Why it was never released overseas is anyone's guess.
Urban Legend of Zelda: Fans were none too pleased about the endings being cut in the American version of Bust a Groove 2. Some thought that because James Suneoka's (a show within a show host) name still appeared in the credits, that somehow, maybe the endings were unlockable. Unfortunately, this wasn't the case.
