"I am frustrated at its slow pace," Bartle said. "There's so much you can do with virtual worlds. But it's not being done. I wanted them to be places of wonder in which people could go to truly be themselves, away from societal pressure or judgement. My idea was that if you could truly find yourself in a virtual world you might be able to then take that back into the real world. Then we could get rid of these artificial restraints of class, gender, social status and so on that dictate that you are what you are born to be."
Bartle talked about how the goal for MUD1 was to give players "pure freedom" and how he thinks that MMOs should operate on a meritocracy. For more information on this topic, check out Massively's MUD retrospective and interview with Bartle back in 2011.
