During his speech at I.Eat.Games, Runic Games CEO Max Schafer revealed that Diablo III was originally conceived as an MMO (Massively Multiplayer Online) game.
Shafer was the co-founder of Blizzard North, the studio that created Diablo I and II before he left and found Runic.
“When I was working at Blizzard a million years ago we were working on Diablo III and it was an MMO. We were going to do the Diablo version of World of Warcraft,” he said. “Blizzard obviously changed that pretty quickly, so we left to start Flagship Studios and we brought in a lot of the guys, so they rebooted with their own team.”
