About 600,000 hours of play have been logged per day on all new, existing, and reactivated accounts, which is pretty staggering. Since the game's launch event players have killed 60 million enemy soldiers and collected 1 billion Divine Tears (remnants of a now-dead god whose death kicked off the current state of the game). While one month is too early to call success or failure, it's a sign that even the older games on the market can still have quite a lot of life in them.
Jagex also posted a video about the new Nightmare Zone, which is content now available for Old-School RuneScape but won't be coming to RuneScape 3 proper. We've embedded that behind the break.
