Bethesda just announced that they will be releasing a "Fallout 3 & Oblivion Double Pack" on April 3rd, for both the Xbox 360 and PC. The Xbox 360 version will set you back $29.99 whereas the PC version will only cost you $19.99. Despite having the "Game of the Year" title to them, they do not come with any of the DLC packs released.
If you've not played both Fallout 3 and Oblivion, this will be your golden opportunity to pick them up in a convenient bundle. I will be posting the link to purchase the bundle when it is released, but for now, get your wallets ready.
