https://techcrunch.com/2018/11/02/world-of-warcraft-classic-demo-limited-to-60-minutes-of-playtime/ > Put away the Jolt, Blizzard is limiting the time gamers will be able to play the World of Warcraft: Classic demo. Basically, after playing for an hour, players will be logged off and will have to wait 60 minutes before resuming for another hour. The goal is to ensure a mass of players do not crash the servers, which, honestly, if the services crashed randomly, would be the most classic thing Blizzard could do to recreate the original WoW experience. > In a forum posting Blizzard says it hopes to lift the session limits as soon as possible.
