Sony Online Entertainment apparently has a hit on its hands as Free Realms has passed the 3 million unique users mark. As the game continues to tick past million mark milestones, we expect to see the four million unique user press release in the next month. If we don't ... something has gone terribly wrong.

To celebrate its latest milestone, SOE is giving out the "3M Pet Party Pack," which has "goodies" for player's virtual feline and canine companions.

As the game continues to grow its base on the PC, we couldn't help but contact SOE and ask about the status of the PS3 version. We were told by a representative the PS3 version is still in development, but there's currently no status update or comment about whether the two platforms would be cross-compatible.
