I'm just not sure I could get into the commitment, to be honest. Being a member of a free company probably comes with responsibilities, and you'd have to at least be semi-active to you know, not get left behind. 
That and the money would be a slight, if constant, sap to my wallet. It isn't really a put off, the money, but it is there. And MMOs practically necessitate a decently powerful desktop with the graphic requirements, and I'm not the most hardcore gamer so I don't have one 
It would be nice if they had like a free to play up to a certain level or amount of time, like a free trial. They probably already do that, I have no clue.
