Being famous nowadays is mostly a challenge. Instead of being recognised for hard work, you're recognised for being recognisable. Getting in the position to be recognised, just known, is more important than talent. Which makes The Sims 3: Showtime an interesting critique of current celebrity culture: if becoming a star is now a gameshow, it takes a game to show that the correct way of doing it is being talented and working hard.
Also: the special edition stars Katy Perry. Here's the bog-standard, non-glamorous version without the gloriously haired Ms Perry.
And now the 100 percent better Perrified Sims Showtime.
Ahem. Sorry. My little joke. This is the Katy Perrified special edition. But I'd totally play a version where you're those guys, polka-ing up awesome pop songs all the way to the top of popular culture.
