World of Warcraft Preview

Games Domain has put together a preview of World of Warcraft, based upon the ongoing beta. Here's a snip to get you started:
There are several areas of World of Warcraft that are still a big question mark. The good and evil races will form some basis for player vs. player combat, but it's not clear how Blizzard will implement this. WoW doesn't currently do anything to drive players into groups, so it's not obvious what sort of communities will spring up and how much the game will require interaction with other players. MMOs also have to balance their appeal for casual players at lower levels and give constant new content to dedicated players who quickly power up to the maximum level. Economy can also be tricky, struggling with inflation, resource distribution, and overcrowding.
