In Guild Wars 2 we have three currencies: gold, karma, and gems. Gold is the common in-game currency. Karma, which players earn in-game but cannot trade, is used for unique rewards. And gems are the currency that’s bought and used to purchase microtransactions.
We have a new player-driven market that allows players to trade gold for gems and gems for gold. If you want something, whether it’s an in-game item or a microtransaction, you ultimately have two ways to get it: you can play to earn gold or you can use money to buy gems. We think that’s important, because it lets more players participate on a level playing field, whether they use their free time or their disposable income to do it.
MMO veterans will note the similarities of our system to EVE Online’s PLEX system. As in that case, our system takes gold trading out of the hands of real-money trading (RMT) companies and puts it directly in the hands of players.
Replace "gold" with "energy credits", "karma" with "gold-pressed latinum" and "gems" with "dilithium", and you can eerily replace "Guild Wars 2" with "Star Trek Online".
I for one have been looking greatly forward to GW2 after being a longtime player of GW1, and I this announcement has not changed my outlook. I am interested how if the ArenaNet / NCsoft version will differ from what we have from Cryptic / PWE (if at all).
