Mainly because it means we can all hang out with the reality star herself - albeit virtually.
Kanye West's missus took to Twitter today to announce the exciting news, with some handy links to the app stores where it's available and she wrote: "Kim Kardashian: Hollywood launches today!"
With it, came a selfie of her avatar from the app, which (of course), looks just as beautiful as the real thing with "Kardashian" written across the top in huge twinkling letters.
Her name was always going to end up in bright lights somewhere.
The 33-year-old reality queen has been teasing her followers with a sneak preview of the mobile app this week, showing cartoon Kim posing on the red carpet, wearing black PVC trousers, a black jacket, heels and a sparkling diamond engagement ring.
Alongside the image, the mum-of-one wrote: "Early look from the #KimKardashianGame launching this week!"
With options like "randomize" and "kustomize" (because of course all C's must become K's in the world of Kim), it looks quite the reality journey.
After creating your avatar, you can hang out with Kim all over the place and basically make all your dreams come true (well, kind of, if they're the kind of dreams you have).
The iTunes description says: "Join KIM KARDASHIAN on a red carpet adventure in Kim Kardashian: Hollywood! Create your own aspiring celebrity and rise to fame and fortune!"
Kim K - whose daughter North recently celebrated her first birthday - had excitedly announced the launch of the app on Instagram, along with a trailer.
The clip shows players posing for photoshoots, choosing outfits for the red carpet, taking to the catwalk, and dating a male star, all watched over by curvy Kim.
Days later, the game was handed odds of 100/1 of becoming Apple's top-earning app.
"We are awaiting the launch with baited breath, but mainly to see if it's as violent as Grand Theft Auto. We are hoping Kim will be dismembering the paparazzi and having fist fights with her momager," said a spokesperson for Paddy Power.
