We still do not know when World Of Warcraft Classic will be arriving but at least we are learning a little more about the game now.
Blizzard has recently revealed that the initial prototype rebuilt Patch 1.12: Drums of War but this lead to several issues including crashes and issues with modern video cards. They then had to build a second prototype that is more stable.
They also revealed in the latest blog post that the re-creation would do the vanilla version of the game justice. Of course, we will have to see for yourself before we can decide if Blizzard is doing the game justice or not but seeing as Blizzard is taking so much time and effort to make sure the game is right, we have high hopes that the end results would be what we want.
