It is also worth noting that World of Warcraft Classic isn't exactly an archive from 2006. It has been rebuilt from patch 1.12, using modern data architecture and reaps the benefits of the modern engine. This means a lot of non-controversial quality-of-life features will still be present and it is possible to run WoW Classic servers on modern server architecture. As you can imagine, much has changed in the last 13 years in the tech space. That's before smartphones were even a thing. The modern engine no longer allows certain behaviours that could be used to get out of bounds, also adds widescreen monitor support and accessibility options! However, it does have the disadvantage of not being able to run on 32-bit systems which isn't that kind to older systems considering the game is from 2006.
CLOSED BETA TEST & STRESS TESTS – Starting May 15, select WoW players will be invited to participate in a small-scale, focused closed beta test, helping ensure WoW Classic nails its goal of authenticity. Players will also get a chance to help put our servers and technology through the paces in a series of stress tests from May through July—opt in now at www.wowclassic.com!
