) anytime soon, and my 360 purchase is 3-4 months away.
I played the Guild Wars demo, and I thought it was fun for a few days, then I lost interest. WoW looks more interesting because I'm already familiar with the world of Azeroth, and I like WarCraft in general.
But, I have a big problem with paying to play stuff. If I'm going to be paying a set fee to play a game, I'll want to get everything out of my money. For people who play WoW, is it worth the money you pay? About how much do you play? I'd have a lot of time to play it on the weekends, as well as Mon./Wed. Plus, it might help me become more organized with studying. I could stay at the library for a set amount of time, and then go home and play WoW for the rest of the night.
