additionally, blizzard released patches for all these games (1.12 for diablo ii, 1.15.2 for starcraft, 1.20e for warcraft iii) which let you play without a cd. this is an unprecedented move in the gaming industry. while most companies are trying harder to increase the drm on their games with disc verification, blizzard is removing discs from the picture entirely. i really hope more companies take this route because going into my disc case to find a disc for a game i want to play is a real pain.

head over to the blizzard store and register an account (if you don’t have one already). once you have verified your email address you can visit the games section under my account controls. from there you can enter your retail cd key for any blizzard games you own which are supported:
