If you have US$ 9.99 and you can't find a use for it, you can now choose between playing for an extra 20 hours The Elder Scrolls IV: Oblivion or take the subway 5 times.

This offer will be available for PC and Xbox 360 owners, as Bethesda Softworks confirmed the Oblivion expansion pack. This additional content for Bethesda's action RPG was originally meant to be exclusive for the PS3, but - as not all of us own, or will own a Sony console - exclusive was turned into available on all platforms.

The expansion pack will be called Knights of Nine, and will be available for Xbox 360 owners later this month, setting them back some 800 Microsoft points, meaning US$ 9.99. The PC version will be a retail one and it will be priced at US 19.99. An Xbox 360 retail version is also in the works, as it results from a Killer Betties interview, revealed by 1up.com.

The PlayStation 3 version of the fourth installment in the Elder Scrolls series, Oblivion will have Knights of Nine -the expansion pack-included, and it will be released on November 17 all across North America. European or Japanese releases have not been announced yet, but there is still hope.
