Champions Online went to the free-to-play route in late January and so far the switch for the super hero MMO from developer Cryptic Studios has proven, at least so far, to be a big success. According to a press release from publisher Atari, the game has seen increases in "online concurrent user, unique login and revenue totals by over 1,000 percent" since the switch. (Specific numbers were not revealed).
This is just the latest example of an MMO game that has seen better success after switching from a subscription only business model to a free-to-play model. Turbine's Dungeons and Dragons Online and Lord of the Rings Online have both reported much more interest in the game since going the free-to-play route.
