So I stumbled over GameBreaker.tv via the Guild Cast podcast. It's kinda like GiantBomb's video content for MMORPGs. A tonne MMORPG-specific vid casts with regular content coming in (and I guess people can participate via live chat).
This episode was quite neat with laying out the basics of GW2's lore and basic gameplay mechanics, as well as some discussions about how PvE endgame will work out. Tune in and check out their shit.
