Fans of Guild Wars have been patiently waiting for a full-blown sequel to the free-to-subscribe massively-multiplayer online role playing game, and from what we saw in its debut trailer, it certainly looks worth the wait. Guild Wars 2 takes fans back to the fantasy world of Tyria and takes place 250 years after the events in Guild Wars, following the awakening of the powerful elder dragons, described by NCSoft as pure "engines of destruction" in the game. If that's not daunting enough, the dragons have also enslaved an undead army to help them in their quest to corrupt and consume Tyria. The four playable races--humans, Charr, Norn, and Asura--have banded together to stop the dragons in their quest, and are joined by some extra help.
