Impossible.
The Elder Scrolls IV: Oblivion
Publisher: Bethesda Softworks | Developer: Bethesda Game Studios
It's no secret that Oblivion is a great RPG. The latest installment of the Elder Scrolls series received very high marks on both 360 and PC and Bethesda has already stated that they intend to keep the RPG consistent across all platforms. Not only will the game run in 1080p it also comes with the new quest "Knights of the Nine" which adds another 10-20 hours of gameplay to the hundreds of hours it already includes. For those of you lucky enough to get your hands on a PS3 at launch, you can revel in the fact that you can take home an RPG that may very well last you until the release of Final Fantasy XIII.
Impossible.
