Best Sidescroller on the scene IMO. Classes are mostly balanced, and pretty much all fun. Skills are unique (animation wise anyway) and the 3d sidescrolling is fun. It's not very grindy IMO if you wanna compare it to games like MS. You do lvl slower than MS, but you get class upgrades and equipment at lower lvl intervals. It has more to do than your standard sidescroller, in that it has mission maps, where you choose a difficulty and run through the mission either by yourself or with a party, and get large amounts of exp. Also has pvp, which is a plus, although PvP isn't the most balanced (I find archer's had a huge advantage in the alpha stage).
CB hasnt been released yet, and I dont think you can get an account (for the IAH version that is), because they basically released keys and approved CB accounts months ago, but then CB was delayed due to them deciding they would use an updated client from the chinese beta for the english beta stage, which they're still playing around with. What CB testers got instead was a 2 week access to an Alpha 2 stage, and the guarantee that they'd be able to play when CB starts...
