Source – According to a Taiwanese Diablo Facebook fanpage, the screenshots below showed what Diablo 3 looked like in 2005. These screens were apparently leaked by an ex-Blizzard North employee. If you do not know, Blizzard North was actually a division under the main Blizzard office. Blizzard North was then closed down by the main office in August 2005.
During that time, the main storyline of Diablo 3 was about the war between Heaven and Hell. This was why some maps are rather bright, supposedly in areas near Heaven. What do you think of the screenshots?
