Now that WoW Classic has been out for a while - which game is being played more, and by how much?
WoW Classic player numbers show a total population estimate of 22.8 million with a daily player number (in April) of just over 1.5 million gamers.
WoW Retail's (Live) Stats
WoW retail player numbers show us a total player estimation of 80 million, far higher than classic but that's to be expected. The more interesting number is the daily players at 2.31 million (in April).
While both sets of numbers are estimations, classic is far closer to retail than you may have imagined in terms of active players. This is during the BFA nightmare, but also a long time after classics release.
