Need a class translation guide, or want the lowdown on what quests and crafting are like? Perhaps the biggest difference between WoW and WAR is a bigger emphasis on PvP of all kinds, and Massively's got the story for you on that as well. If you've been interested in checking out Warhammer at all (or if a few friends have mentioned they're switching), this guide will bring you right up to speed.
Of course, even EA admits that Warhammer won't really be a rival to World of Warcraft, but there's no question that the game has already influenced how even Blizzard makes its games, so no matter how many players choose to cross over, there's no question the new MMO on the block is going to make a splash. The game comes out in just over a week on September 18 -- if this guide has piqued your interest, stay tuned to Massively for more on what's up with the game and its release.
