This paragraph was in the middle of the post linked to above:

"When we originally started work on the engine back in 2002/2004/2006 we had the intention of developing only an engine and making it available to the public. This is a daunting task in itself and is not our focus at this time. The engine may one day become available for sale but that would be years down the road from where we are now as running a mmorpg is enough work in itself."

 

 

Maybe those other people bought the game engine?
