Abstract
There are two types of game billing systems: those in which payment is closer to winning and those in which no winning is involved. They are called P2W: Pay to Win and P2F: Pay to Fun. It is not clear what users think of these and how they pay for them. We conducted a qualitative study on what users perceive as P2W and P2F billing. As the results, that they are motivated by "efficiency," "eliminating difficulties," and "pride maintenance" for P2W and "efficiency," "special to me," "project support," and "collection" for P2F respectively.
