Last year’s XCOM: Enemy Unknown was amazing. It kept me enthralled for over 60 hours. I even managed to save humanity a few times, and while I was having fun each time, my campaigns always followed the same arc: tech up to laser weapons, tech up to carapace armor, capture and research plasma, research ghost armor, discover psionics and save the planet. Things didn’t always go according to plan, but when they did, that was the order of operations. XCOM: Enemy Within shakes things up quite a bit, and it makes every aspect of the game feel fresh again.
