[quote]EXP – In game Currency used for just about everything, from buying starter equipment to leveling up to purchasing Land Claims. EXP can be earned from slaying Dissolutions or players, but it can also be obtained by breaking down items in your inventory or just found anywhere within Deep Ground. Exp takes the form of floating colored crystalloids. There’s no real meaning behind the colors.[/quote]

From the OP.

All things considered, it's still a government-monitored education program or whatever. Guessing that being able to pay for EXP using RL money would be similar to bribing professors to look the other way while doing your final exams. So gotta go backdoor~
