Meryl Silverburgh, Metal Gear Solid
The great thing about Solid Snake's relationship with rookie sidekick Meryl was that you could decide her fate. If you resisted Revolver Ocelot during Metal Gear Solid's infamous torture scene, Snake rescued his damsel in distress. If you submitted to Ocelot's torture, however, then poor Meryl bit the dust. This, obviously, wouldn't do. How many replayed the game, spurred on by an overpowering crush on Meryl, to see her safe? Just us then.
