In the cash shop world, it is accepted that many players spend money on virtual items. It is discussed here and there, and in some games is talked about as though the items might be "unfair," but overall the attitude is "anyone can do it, so be it..."
Mabinogi is no different. I spend a great deal of time in the game, and players rarely even discuss the cash shop... at least in the populated towns and in discussions with me. Granted, they could be staging protests that I am not invited to, but I doubt it. Most players are simply playing the game.
Why is it that most players (in cash shop games) don't worry so much about those players that spend real life money on items, while players in non-cash shop games seem to speak of the cash shop as though it is the end of the world?
