For disc versions or botched official releases gamecopyworld still seems to be there. Back when games still came on discs, i downloaded the crack even before trying to install a freshly bought game.

Ofc, this is mostly a moot point now with GoG. If GoG manages to convince the publisher to let them sell the game without DRM.

Edit @stavros: You and anyone suffering from nostalgia should check GoG regularly :) I probably have most of my childhood games on there now.
