You dont Have to. It would just be eaiser to get money that way. If u didnt, ud spend half ur time just getting a thing called *sweat* and it sells on the PE market for .02$ or 2cents. So, if u would rather get into the game faster, use ur money. If u want to run around getting sweat, go ahead, just warning u now it will bore the hell out of u if u do:S I went through the same thing, but in the end, i uninstalled the game lol. Its not a bad game, just it really should be called, pay to play, cause if u didnt, all ud be doing is hunting for bottles of sweat.
Imo, PristonTale is much more fun.
