WoW Classic released legally on August 26, 2019. For the most part, it is the game as it was in version 1.12.1 (September 2006). At this point in time, it is unclear if it will remain that way, effectively acting like the version selector in minecraft, or if future content will be developed, more akin to oldschool-runescape.
How do we want to approach tagging these questions? We could create a new tag for it, or we can use the existing world-of-warcraft tag. I created world-of-warcraft-classic before realizing that it didn't exist yet, and want to make sure that we don't create a large cleanup effort for ourselves down the line anyway.
