The Warhammer Online: Age of Reckoning Beta has been going on for quite some time now, but IGN hasn't been able to talk about it much until very recently. Overall, they think the delay between their first unrestricted play session and the green light to write about it has worked in the game's favor. It's not that Warhammer Online doesn't make a good first impression; the game's unique strengths are readily apparent within the first few hours of play.
The real benefit of getting a chance to run through several levels of content with a variety of characters is that IGN hs a much better sense of the overall big picture of the game and have come away impressed that the things that are fun at level 1 are still fun at level 20. There are obviously still some issues to address, but the overall appeal is undeniable.
