Gameplay: One of the best aspects of this game. Out of all of the MMORPG's I've played, this has the most involving and plain fun gameplay. While it is not all that inventive in it's layout and skill trees and such, it impliments them very well and works very smoothly.
Graphics: This game is a gem in this department. It's amazing how an all online game could have graphics like this. Near perfect.
Sound: Solid sound that fluctuactes with what's going on around you. A few nice themes, implimented seamlessly
Story: Being the beta the story wasn't complete, and I didn't actually get tot he end of any characters storyline. This will definately go up once I play the full version and get further.
Replay Value: With 8 races each with their own land and story, this could easily eat away hundreds of hours of your time. And it will.
Overall: This is looking to be a very solid game, and the best online RPG around. Blizzard's done it again. With a few thigns tweaked and added on in the full version, this game could rank easily in the high 90's. A must have.
