Think about games that you never thought would be made. Ever, in the history of anything. Does a game based on Grease, the classic John Travolta/Olivia Newton-John movie, pop to the top of that list?

Well, it looks like you’re wrong. (Not sure if I should be amused or empathetic about your failure.)

505 Games is turning the classic Paramount Pictures musical into a game for the Wii and Nintendo DS and DSi due out this September.

The Wii version is a family-friendly party game featuring 16 of the movie’s songs, with a Party Mode that lets you compete in teams using the Wii Balance Board and USB microphones. You can sing about how “Grease is the word,” play carnival games just like at Rydell High’s graduation celebration, race against Greased Lightnin’ on Thunder Road, or just plain dance your socks off at the sock hop.

If Story Mode is more your thing, you can fix up the car and try to woo Sandy.

Now, as far as the handheld versions go, you’ll have the option of a story mode following Sandy and Danny (which also features songs from the soundtrack as well as dance steps from the movie). Unlockables include special costumes and songs. You’ll be able to experience multiplayer with either multi-cart or download play functionality. If you’ve got a DSi, you can even use the camera to get your face in the game.

505 Games is calling this an excuse to have a party, but I would probably be a lot more likely to hide the box in a closet so none of my friends would find it at any parties that I do have. (Our parties skew more towards the Rock Band form of entertainment.) What about you? Do you think that playing a Grease video game would be fun? Or does it veer a little more towards being ridiculous? For the extreme fans of the movie looking to get their kids into it, this does make sense, at least.
