A couple of years ago I was introduced to the world of MMORPGS (Massively Multiplayer Online Role Playing Games). I played City of Heroes and City of Villains enough to familiarize myself with the whole MMO gameplay experience. I wanted something more and had friends who loved World of Warcraft. So I decided to try it out and bought World of Warcraft. I loved the game enough to then buy the Burning Crusade expansion pack when it was launched so I would be able to level to 70 as well as play new races/see new content.
Some basic things for those who have never played World of Warcraft: 1) You must pay $14.95 a month to play. 2) This game can be highly addictive and definitely needs to be taken with a grain of salt when it comes to the time you invest. 3) To get anywhere end-game you WILL be spending a lot of time on this game, so be prepared for that.
I love World of Warcraft, I loved the expansion. Flying mounts, new instances, new gear, new PvP, etc. but because of the draw-backs I'm going to mention now, I no longer play. This game will take a lot of time, and once you hit 70 you enter into the world of raiding and rep grinding. Rep grinding was recently patched to be much less tedious and time consuming, but it's still a pain. You need to grind rep with several factions to get access to Heroic keys (these keys unlock dungeons, making them heroic, meaning they drop better gear and are much more difficult). Raiding can be a massive time consumer because you must 1) Be part of a large guild and 2) Must agree to spend several hours during the week, sometimes daily to attend said raids. One of the big reasons I ended up quitting WoW was because I just didn't want to make the game my whole life. I love the game, enough to have two level 70 characters, but I was not willing to spend every waking moment playing it. I was in a very large guild and every time I'd log in I was called to run something or sign up for a raid. The whole point of this game is to get gear. And it becomes tedious and feels very unfufilling after enough time has passed. It got to feel like a second job having to sign in and hack away for hours just to get one or two new pieces of gear. Basically, the friends and fun I had when I started were starting to become more of a chore than a fun game to pass my time. So I had to quit.
But! That isn't to say this game isn't awesome, because it is. It's just time consuming if you LET it be. I ended up quitting for a few months and then returning, quitting my big guild and stopped raiding. It made the game more fun for me because I was just running things with friends, like when I'd first started. And I quit after this mainly because I couldn't see the point in paying $15 a month for a game I hardly ever signed in to play anymore.
If you love WoW, or have never played and want to, I'd recommend completely buying the Burning Crusade expansion. You NEED it to get anywhere past 60, plus, it just has so much more content that you'd miss out on. But be warned, this game can suck you in. If you've got the time to kill, go for it!
