In my opinion wow is worth the money (but that's my opinion,) i would get the trial play until level 20 (i would make a few chars and get them to 20) the decide if you like it or not. Wow is not that addictive i have had it for a year now and im not addicted i go on most days just to do something for few hours and chat to friends.

1-20 is the most boring part of the game. Wehn you can do good dungeons, pvp, and raid is when it gets fun. So just a heads up
