The discussion is flowing back and forth about virtual property and real world markets. In the discussion about the limit between work and play ended up more or less uncontested defined as "It isn't work if you enjoy it". At the same time there seems to be a problem with people making money off the games, because that ruins the borders between the games and areas like ebay where game objects are sold.
I miss an important aspect here. How does all of this compare to sports? Are sports work or play? Are professional athletes sportsmen or labourers? Is the player who makes money the dystopian gambler or the ideal athlete?
I think I want somebody, soon, to discuss gaming and sports. There is a link there which might be beneficial to the game studies.
