World of Warcraft is simply put, the best MMORPG ever created. Blizzard spent a good amount of time creating and testing this masterpiece, and it shows off. No matter what type of games you like to play, you'll like playing WoW. Even if your PC isn't blazing fast, you'll get perfect quality out of WoW. Everything in the game just feels right.
Let me split my review into sections;
GRAPHICS
--------
The graphics in WoW are a splendor to behold. The textures and geometry are excellent and really show how much detail Blizzard put into this game. The visuals aren't DOOM 3 or Half-Life 2 in extreme quality, but this is a MMO with quite a bit of people and low system requirements. The shadows, weather and particle effects, and 'bonus' graphical work (such as footprints in the snow, etc) are above average. With all the visual settings maxed out, along with my graphic card's hardware AA/AF maxed, the game does not stutter, even on my mid-range PC. I'm amazed I can have everything maxed, having my screen look gorgeous, and have perfect v-sync frame rates constantly.
SOUND/MUSIC
--------
Music in WoW is, of course, spectacular. Blizzard is known for having awesome scores that are dynamic and suiting. There's a ton of different scores that dynamically change depending on where you are and what's going on, and they're all near-godly and memorable. The sound design is also great: each individual sound effect and voice sounds like what it should. No complaints in the sound department.
SERVERS
--------
Blizzard has a good amount of servers setup. Quite a lot of them, in fact. Not only that, but there's specific servers for PvP, so you can be on one of those if you enjoy dueling. PvE servers can have PvP game play as well, but both parties need to agree beforehand. The servers are lightning fast and I've yet to have downtime.
COMMUNITY
--------
So far, I've experienced a nice community in-game. I've played three different races and the communities in each of them (almost each race has its own starting location in the world of the game) have been very nice, considerate, and helpful. Granted, not everyone acts as they should, but I've had an enjoyable time with the community so far.
INTERFACE
--------
I really can't think up a way Blizzard could improve WoW's interface. It's mildly complex and takes a bit to get used to, but once you get over those first minutes it feels like second nature. Chatting is simple and fun, with numerous functions. Everything about the game is clearly described, explained, labeled, and shown in the manual and in-game. There are also tips that help you with just about everything as you experience it the first time.
GAMEPLAY
--------
The most important part of a game and WoW does it great. There's so much to do in the GIGANTIC world that you won't want to stop. Just a few of the 'professions' you can do: cooking, fishing, mining, blacksmithing, first aid, and alchemy. Besides all those you can just do the 2000+ quests, level up your character, join groups, create or join a guild, and more. It really is like an online world, and it's addicting. The quests range from extremely simple to very advanced, with plenty to choose from. The races are distinct but balanced, and each one has its own feel and flavor. The classes are well balanced also (except for Warrior, which is pretty underpowered, but Blizzard has said they're already working on it for the next patch). There's enough classes and races to suit anyone's taste, and there's definitely enough so that you can have multiple, different characters without feeling bored. The pace of the game feels just right; not too fast, not too slow. Death isn't a huge hassle, quest rewards are actually rewarding, the races are cool and different, the classes are exciting and aren't disappointments or unbalanced, the game is as simple or nearly-overwhelmingly complex as YOU want it to be, Blizzard's support is fantastic, and there isn't a single feature left out of the game. In a word: perfection.
All in all, WoW is definitely one of the best gaming experiences I've had, and I haven't even come close to experiencing it all. If you like Blizzard's previous games, role-playing games, and/or other MMOs, you'll love WoW for sure. Even if you don't like those, there's still a very high chance of you falling in love with it, since it's just so damn fun to play.
The monthly fee is well worth the countless hours of bliss you'll receive, and they provide discounts when you pay in bulk, like 3-months and 6-months.
I recommend buying the strategy guide (more like strategy tome, it's over 400 pages!) if you're new to MMOs, since there's a lot to learn. The game's manual is thick too, and there's plenty of in-game and online resources available.
If you can find it, purchase the Collector's Edition since for $30 more you get quite a lot (the game on 4 CDs, the game on 1 DVD, the soundtrack, a large making-of book, an exclusive in-game 'pet,' and more).
World of Warcraft is a game I very highly recommend for everyone to buy and experience, even gamers who don't like online play.
