Here's a random thought: will there be a Mariah Carey video game? Her songs may not work well for Guitar Hero, but I think some sort of karaoke game
might be fun.
There's a game called Def Jam Fight For New York where you can play as and beat up a bunch of rappers including Snoop Dogg, Ludacris, Flava
Flav, Fat Joe, Freeway, Lil' Kim, Ice-T and Method Man, among others.
They should make one with just divas. Snoop's the end level boss in Fight For New York, so Whitney Houston could be a cracked out drug lord as the final
boss in the divas one.
