If you love something, set it free... because then tons of new people will be willing to give your game a chance. Sony Online Entertainment recently transitioned its DC Universe Online MMO into a free-to-play game, and has been rewarded with 120,000 new players since the relaunch.

According to SOE president John Smedley, there's been a 300 percent increase in the number of concurrent players online. However, the player boom has introduced a number of server problems.

PC Gamer reports that servers are having "stability issues" even during non-peak hours. The site estimates that thousands of players are waiting to get in and play via login queues, a consequence of DCUO's "super servers" that allow all players to play on the same realm.

The issues will, hopefully, be ironed out as Smedley promises a "big TV and online campaign" later this month, promoting the F2P switch. Given the appeal of the DC Universe, a free-to-play MMO is likely to have quite the casual appeal.
