A new version of World of Warcraft was just discovered and it's called "World of Warcraft Camelot". Instead of some kind of Arthurian spin-off, however, the dataminer who found it theorizes that it's just a codename for an enhanced version of World of Warcraft Classic.
Dubbed "WoW Classic Plus" by hopeful players over the years, this hypothetical version of the MMO would branch off from the original and become something new based on something old—just like Old School Runescape.
