The game will follow the standard "buy the box and then pay subscription" trend common among MMORPGs, but will also introduce to its players a unique way to buy game time. The in game item C.R.E.D.D adds a month of game time to your account when activated. C.R.E.D.D can be purchased by in game currency from other players, or with real life money, but for a higher price than then standard one month subscription fee. This strategy is in place to help fight against the illegal gold farming trend, common in almost every MMO. Players who wish to buy in game currency with real money can instead buy C.R.E.D.D, and then sell it in game for in game currency.
And yes. This also means that there is the potential for players to never have to pay subscription fee after the initial purchase. Whoopee! Technically F2P!
Frankly, I think this is a genius move by NC Soft, and I'll most likely pick it up when it releases.
Mind blown
