Blizzard turned 30 yesterday. In honor of the anniversary, the company shares early concepts of its classic games, including WarCraft and Diablo, on social networks.Blizzard publishes archival materials in the official Twitter accounts of World of Warcraft, Diablo, StarCraft and Overwatch under the hashtag #FromTheVault.

The company, for example, showed one of the first variants of the WoW user interface. If you compare it with the latest and even the release version of the project in 2004, you can see how much it has changed.

The drawing is dated 1996.

This is how, for example, the early class concepts for Diablo looked like: warrior, robber and mage. The author of the images is the artist Roman Kenney.

Now the company is preparing for the BlizzCon festival, which will be held online for the first time and will also be timed to the 30th anniversary of the studio.
