Hello, So, after being addicted to WoW for... 6 months, and with college/university coming next year, I have decided that I need a new game. What I am pretty much looking for is something that I can pick up and play for 20 minutes once and a while, or when I have time to be able to play for 4 hours and up without getting bored. I have found WoW to be a huge time consumer, and you can't really play for 20 minutes. Recommendations? It can be for PC or Mac.
