Baldur's Gate Trilogy (Baldur's Gate + Tales of the Sword Coast + Baldur's Gate II: Shadows of Amn + Throne of Bhaal).

The world is huge, the combat is hard, the magic is awesome and the story is the best that BioWare has ever come up with. For me, it's the best all-around CRPG I've ever played.
Morrowind would be a distant second.

Fix their home team score on the board to the debt clock, they can win every game 17,000,000,000,000 to 24. Losing team gets taxed by the IRS 100%, then droned."
