I am not sure if mmo tourists care more about a game being B2P or F2P than the average consumer. The people that go from MMO to MMO are stuck in a hype cycle and its' really the hype that they want to play rather than the game. It would be nicer if that hype cost them less, but even the cost question becomes a part of the cycle. One month its F2P is the future, next month is Subs are the only honest way,and then the next month is all subs are a scam because everything is F2P anyways.
Basically, for the mmo vagabond to have a solid philosophy and view on what an MMO should cost would require a level of reason that they just don't care to have.
