writes "While old school geeks & gamers know that Warhammer predated Warcraft, there are many MMORPG fanatics these days that don't know the history of both franchises, and comment that Warhammer Online resembles World of Warcraft. OGX has an article about this very question with some input from Mark Jacobs (Studio GM EA Mythic, VP EA)."
From the article: "This history factors heavily in the present situation wherein the Warhammer Online game looks, to many, to be a descendant of the success of World of Warcraft in a market filled with many games trying to be just that. It's easy to see how this confusion would arise, and I asked Mark Jacobs, Studio GM EA Mythic, VP Electronic Arts, to share his thoughts about the situation."
Warhammer may have influenced WoW, but WHO's interface still looks like a WoW rip-off to me.
