One of the best games of the past 10 years, just not great....
It was a very well put together rail game. It was smooth and beautiful. Very few bugs and issues. Blizzard really did a good job with quality.
It's not an MMO. WOW is a rail game, plain and simple. To put it another way its "The Legend of Zelda", in 3d, with Warcraft characters. With few exceptions you can play this game completely by yourself, without any other players. The online element was completely wasted. Then after dozens (or hundreds) of hours in game you suddenly are required to join up with other players for "optional" quests. Why even bother?
For many gamers there was nothing to this game but hours upon hours of attack keys and grabbing pointless loot. Some people love that, many of us hate it!
The Bottom Line
If you haven't played an action game where you gain levels before, this game will be a very good start. But if you have spent anytime in level gaining games, monster stomping + loot grabbing, or anytime online in a MMO over the past 20 years, then this game will a complete repeat of previous games. Except for very few instances, you do not even need to speak or deal with other players. WOW could and should be a single player game. The online element is a huge waste of resources for both the development and the player.
