“We talked about it [making Classic] for a number of years and we couldn’t figure out what the right way to do it would be,” Brack explained. "The problem was, the codebase that shipped with WoW and encompassed the WoW Classic timeline was a codebase that we had really moved on from in subsequent years. Software is a very iterative process, and its development was more than 10 years in the past at this point. So thinking about the hardware that didn’t exist anymore that we would need to run on it, running two MMOs simultaneously with two different toolsets, two different toolchains, it was not something we could really get our head around.”

Before work began on World of Warcraft: Classic, it was only possible for players to experience the original World of Warcraft by using private servers, which are illegal, often have stability or corruption problems, and generally are very imperfect recreations of the authentic World of Warcraft experience. As much as Blizzard has been aware of the desires of their community, until recently it seemed impossible for them to emulate Classic servers due to the technical hurdles of essentially having to run two massively multiplayer online games side-by-side. A breakthrough was then achieved that made it possible to run Classic servers on the modern architecture of current World of Warcraft servers.

I commonly see things like "zomg blikky made 12 bazillion dollars last financial year" "haii why so cheap daddy blizz, please release 500 low pop servers on release , so you can spend the next year wasting money and resources " Grow up. Thanks.Azerothian30 Nov 15
Notez que lors de la sortie du jeu, le mardi 27 août 2019, tout le contenu ne sera pas disponible immédiatement. Celui-ci sera déployé en 6 phases. En effet, les développeurs souhaitent attendre et voir comment la communauté s'approprie le jeu. Blizzard partagera le calendrier lorsque que les développeurs auront une idée plus claire de la façon dont les joueurs profitent du contenu. Nous vous proposons un calendrier qui sera mis à jour dès que les informations seront disponibles.
