In a Tweet tonight from Alan "Brenlo" Crosby we discovered that Free Realms now has 3 million registered players. 

For those counting, Free Realms launched in the 11th hour of April 28, and hit 1 million registered players a mere 17 days later.  Players were still enjoying their 1 millionth player goodies when the game hit 2 million players less than 30 days after launch.  Now here we are, 45 days after launch by my count, with an unofficial announcement that we have hit the 3 million mark! 

Looks like SOE has hit it out of the park with this one, folks!  Congratulations!
