World of Warcraft Review.
Firstly lets talk about the PvP. In pretty much every MMO out there PvP is either a hit or miss situation. Blizzard hit dead on with World of Warcraft's PvP system. If you prefer a fast paced get in there and kill stuff PvP style, WoW has battlegrounds just for people like you who want quick paced PvP. Or maybe you prefer your PvP over a large area? Just go out into zones find some players of the opposite faction! Of course you can't just go kill whoever you want. There are however, different realm styles. In a PvP realm there will be more players who want Player vs. Player action, and also you will be able to fight other players in more zones than a normal server or an RP server. And that brings me to Role-playing and Guilds.
Maybe PvP isn't for you? Maybe you would rather work on making money or Role-playing with friends? Well World of Warcraft is still the game you want. In a Role-playing server you can go into your local inn and have a friendly in-character chat with your fellow players. In any type of server you can join a guild, which is basically a group of people who have similar interests in the game. So WoW can be used to get into the PvP action and pwn up on some noobs, or you can choose to just use the game just to be social and hang out with friends.
Or maybe you don't care about PvP or talking to people and just want to watch your character kill monsters, progress in level and skills, and explore the world? Well WoW has that also. With many classes to choose from and different ways to play each class you'll be able to make your own custom character to explore a massive landscape in the world of Azeroth. Your character can learn up to two professions, which offer huge amounts of things to do. You can be a miner and search around for mineral veins to mine, or maybe you want to be a leatherworker and make armor out of the skins of your foes? Either way WoW is the game for you.
To end my review I would like to say that no matter what you want in a MMO, World of Warcraft has it, and has a better version of it than any other MMO on the market. There have been many games out come out to rival WoW, and although some have gotten rather popular, none have ever done what World of Warcraft has.
World of Warcraft has been, is, and continues to be, the best MMO on the market.
Period.
