I don't know if anyone here uses Steam much, if at all, but there are some good deals on some great RPG's at the moment.
They are all Betheseda game deals because of the impending release of Fallout New Vegas which is now available for pre-order.
Fallout 3: Game of the Year Editions is $24.99.
The Elder Scrolls IV: Oblivion Game of the Year Edition Deluxe is $8.50
The Elder Scrolls III: Morrowind® Game of the Year Edition is $5.
