I find this game fun only because I play along with my Brother and some of his and my friends. If you don't play with anyone you know in real life I'd recommend finding an active guild because this game is pretty boring when you play all alone.
Have fun and good luck though if you do get into it.
BTW, it doesn't take over your life or make you kill yourself, etc. Just limit your play time to about 2 hours (I play around 2 hours a day... probably less if I'm busy). But don't be someone who stops doing homework and stuff just to check your auction house items.
