I got in on the beta event this weekend and was pretty impressed. It's mostly WoW crossed with Warhammer (spontaneous world quests/shared quests) with a touch of Shadowbane. (the customizable talent specs.) It looked pretty, and a nice change from the semi-cartoonish graphics in WoW. The server was really stable and aside from a minor queue I had no performance or access issues.

Imagine WoW where you can choose your talent trees and each of those trees are deeper and appear to be more interesting than the cookie-cutter-ized Cataclysm trees. The game ran amazingly on my rig (I have 3 monitors in eyefinity an play wraparound at 6084x1020 when I'm not multiboxing.) Leveling seemed pretty painless, but I was so busy re-rolling to try new combos, I never got past lvl 15 with any of them.

I'm definitely going to be playing this and probably dual-boxing it...once ISBoxer supports it. :^)
