it's a gas

Something to spend $$ on maybe - not monthly subscriptions but... in this article...

Microtransactions will be properly introduced in Guild Wars 2 enabling players to purchase in-game items with real money, though this won’t be mandatory. This system works with a lot of games, though some like Need for Speed world require a minimum purchase to get the most out of the game. It’s a good model for people who want to play MMORPGS more casually, rather than those who play constantly because they have a subscription.
