John Smedley, SOE's President, announced on Twitter this morning that over 330k new players have signed up for their action-RPG MMO DC Universe Online on the PC since the game transitioned to free-to-play Tuesday evening. In the same tweet, he announced that the number of concurrent users logged into the game has increased 600% in that same time, and that they’re planning to launch a massive TV and online ad campaign later this month. He did not mention any numbers for PS3 users.

Of course it’s not all daisies and roses for players trying to get into the game during this massive spike in activity. Even during non-peak hours, servers are having stability issues and, anecdotally, login queues have thousands of players waiting to get in and play. SOE loves to boast about DCUO’s “super servers” that allow all players to all play on the same realm within the game, which has a lot of awesome benefits (like never having to pay to transfer servers and always being able to play with your friends who are online), but hopefully they can resolve these stability issues before too many people run away from the game because of them.
