The Warlords of Draenor expansion is looking to be the most fun and noob-friendly I've seen Blizzard make World of Warcraft. The game is finally in a state where I can genuinely recommend it to a new player. Check out these videos from Blizzard with short and neat intros to the available classes. Maybe one of them is something you'd want to play!

At $15 per month, WoW is by far the best bang for the buck you'll get for an entertainment hour. Hookers, restaurants, theater, opera, cinemas, bars, and legal and illegal drugs can't compare with that bargain. What I can't promise, however, is that you won't want to play too much. :)
